           This is a FAQ - a Frequently Asked Questions list. These are
           written and posted to newsgroups to cut down on needless
           repetition of questions that everyone, bar the ignorant
           questioner, who is never a regular reader of the group, knows the
           answer to by heart.

           You can find many of the other FAQs in existence by:
           a. reading the *.answers newsgroups.
           b. searching back through newsgroups for the title 'FAQ'.
           c. ftp'ing to rtfm.mit.edu. If you don't know what ftp is, ask
              your systems administrator. If you don't know what rtfm means,
              you really do need to read some FAQs.

           There are a number of Macintosh-specific FAQs, posted regularly
           in comp.sys.mac.* and archived at rtfm.mit.edu (directory
           pub/usenet/news.answers/macintosh), umich and info-mac (directory
           info-mac/info). Anyone reading comp.sys.mac.whatever should have
           read through these FAQs at some point. Check the FAQs to see if the
           question you are about to ask has already been answered for you.

           This FAQ list addresses problems Mac screensaver users may have.
           In doing this, this also answers some common questions new Mac
           users have, which are not related to screensavers, but which are
           asked so often it's worth pointing out that the answers are there
           for you to find. The answers to these questions have been
           prefaced with 'FAQ alert!'. Look for it.

           These common questions are:

           How can I change the name of my hard disk? Why does my hard disk
           look like a blank page? How can I get colour floppy disk icons?
           See 'Other things FileTyper is useful for' at the end of (4.0).

           How can I get a picture of the screen? With the cursor and menus
           visible? See (0.3).

           Where can I find system software updates? What reads the disk
           images? See (1.1).

           What is Macsbug? Where can I find it? What do I do with it? How
           do I use it? See (5.0).

           Where can I find Mac stuff on ftp sites? What do I need to
           interpret the files? How can I send stuff to these ftp sites for
           others to share? See Introduction.

           Are viruses a problem on the Mac? How can I deal with them? See
           the entry for Virex-D under (5.2).

           My PowerBook's hard disk spins down. Why doesn't my desktop
           Mac's? See (0.0.4).

           How do I get a working Brightness control panel? See (0.1.2).

           FAQ alert! The major Mac-specific anonymous FTP sites mentioned
           here, which provide the world with Mac freeware and shareware:

           sumex-aim.stanford.edu (sumex) - the home of the Info-Mac
           archives (info-mac). Many mirror sites worldwide. Any file with a
           path starting 'info-mac/...' is on sumex or its mirrors. See the
           Info-Mac Digest in comp.sys.mac.digest for details of new Mac
           software available here.

           mac.archive.umich.edu (umich) - not related to sumex. Many mirror
           sites worldwide - ftp to mirror.archive.umich.edu to get to a
           mirror in the US. See the regular newfile postings in
           comp.sys.mac.digest for details of new Mac software available
           here.

           ftp.apple.com - Apple's own software archive on the net. Here you
           will find system software and updates, utilities and gadgets
           written by Apple's engineers, and development material. If you
           don't have access to AppleLink, this is *the* place to look for
           new system fixes and free copies of system software up to 7.0.1.

           A complete list of Mac ftp sites of interest can be found in the
           mac.ftp.list in info-mac/info. It is posted regularly to
           comp.sys.mac.misc, .apps and .games by Bruce Grubb
           <[e-mail]>, and is available on the Web (see below).
           Advice on how to find and download Mac files, and get them into
           your Mac, is also given.


           This FAQ is crossposted to most of the comp.sys.mac.* newsgroups
           on an irregular basis whenever it is updated. A copy can always
           be found for anonymous ftp in info-mac/info/sft.

           If you have access to the World-Wide Web, you can find this FAQ,
           along with other Macintosh FAQs, on it. Here's the URL:
              http://www.astro.nwu.edu/lentz/mac/faqs/home-faqs.html
           Thanks to Robert Lentz <[e-mail]> for providing
           this service to the Mac community.


           This FAQ answers common questions about screensavers for the Mac.
           What's available, where you can get them from, and whether or not
           you need a screensaver are covered. Most of this FAQ pertains to
           the most popular commercial Mac screensaver - AD from BS, the
           modules available for it, and other screensavers capable of using
           its modules.

           The FAQ details common AD problems and misconceptions,
           concentrating on 'Why does AD crash my machine?' The answer is
           almost always either 'You need to get and run the free 2.0x
           updater' or 'You are using a badly-written third-party module
           running under the MultiModule or Randomizer modules'. These
           modules impose stricter rules on how a module can run than AD
           alone does, and a large number of third party (shareware or
           freeware) modules either crash the Mac or won't run as a
           sub-module.

           How to update AD is given in (1.0). A list of 'problem' modules
           that should not be run under MultiModule/Randomizer is given in
           (5.0).

           Although many have requested it, this FAQ does not attempt to be
           a canonical list of all the AD modules in existence. I don't have
           access to the online AD forums in the US. I haven't seen a number
           of the commercial packages or the books. I can't sneak into BS's
           labs, on the other side of the world, in the dead of night, to
           look at all the competition entries. (Heck, I couldn't afford the
           trip.) I estimate I have seen less than a third of all the
           shareware modules in existence - and I've been working at it. A
           definitive list of modules is simply not possible. If a module is
           not mentioned here, that's either because I haven't seen it, or
           because I have seen it, but haven't found a reason to mention it
           or found a problem with it on the Mac setups available to me. You
           might, and I can't call a module 'good' simply because it works
           fine for me.


           [FAQ alert! If you want to spread good Mac shareware or freeware,
           including AD modules, to the world, giving millions of people,
           including me, the chance to see it, simply email a binhexed copy
           of the compacted or stuffited archive to:
              [e-mail]
           which will distribute it to ftp archives across the world,
           including the big ones - info-mac, umich, their many mirrors, and
           comp.binaries.mac. Remember to add a text description of the
           contents before that long binhex column!

           Don't send self-extracting archives (SEAs) - Compact Pro, Stuffit
           Expander and Stuffit Lite are readily available from these ftp
           archives, and we all know how to use them. Dial-up access to ftp
           sites is on the increase and SEAs run up others' phone bills
           unnecessarily.
           Compact Pro is now at v1.34.
           Stuffit Expander and Lite are now at v3.07. The old Stuffit and
           Unstuffit v1.5.1 cannot read the new, more efficient 3.0
           format. Trash them and upgrade.

           Find your local sumex (info-mac) or umich mirror, listed in the
           mac.ftp.list detailed above, and use that to download new
           software, rather than tying up distant sites.]


           The information in this FAQ is based on my use of AD, DS, MAD, SS
           and ST, and on tidbits I have gleaned from email from many
           writers and users of screensavers and AD modules.

           I welcome comments and corrections, hints on using specific
           modules, and tips and compatibility information relating to other
           Mac screensavers.

           Despite the emphasis of this FAQ on AD modules, I have no
           connection with BS other than as a user of their products. I'm
           declaring the T-shirt BS gave me for generously saving them a
           fortune in tech support, though. Nothing underhand here.
           [I welcome free clothing, and promise to wear it around a busy
           campus. Tap your UK market!]

           This FAQ does not cover the use of AD on the Windows platform -
           it's for the Mac version (and other Mac screensavers) only. There
           is no way to convert Windows AD modules to Mac AD modules without
           extensive rewriting of the source code - it's a job for the
           authors of that module, and few have experience of programming
           Windows AND the Mac. The Windows AD comes with different modules
           to the Mac version for this reason. Module ports are unlikely.





   DO I NEED A SCREENSAVER? (0.0)

           Despite what many people will tell you, the answer is almost
           certainly 'no'. Screen phosphor burn-in on CRTs is not the
           problem it is made out to be. Damaging a modern CRT with a
           burnt-in still image is very difficult to do, and takes a very
           long time.

           If you really are worried about preserving screen phosphor,
           either:

           a. Turn your monitor off when you are not using your Mac, so that
           the phosphor is not in use at all, and cannot possibly be burnt.
           This has the desirable side-effect of saving energy and
           decreasing your electricity bills; ES does this for you
           automatically. See (0.0.1).

           b. Use a simple, boring, black screenblanker, as this does a far
           better job of saving phosphor than any animated pattern in a
           screensaver package can, and, unlike those fancy screensavers, it
           might even save you some electricity and some money. See (0.0.1).

           It takes a very long time to burn the phosphor on a cathode ray
           tube with a still image - accidentally leaving your Mac on all
           weekend won't do it. Old Mac Plusses or monochrome Mac monitors
           that have seen years of service may have a ghostly bar at the top
           of the screen from the menu bar, visible when a menu bar is not
           present, but that's about it.

           The phosphor on colour monitors is even more difficult to burn,
           making screensavers even less useful than you may think. Anyone
           worried about the menu bar burning in on their colour monitor can
           use Aurora 3.0 (in info-mac/cp) to give a white-on-black menu bar.

           So why do all these screensavers exist? Most commercial
           screensavers are marketed as entertainment; most standalone
           downloadable screensavers were written as fun programming
           exercises. They're entertaining toys to play with.

           A screensaver can be useful for protecting your Mac from prying
           eyes while you are away from it, and many screensavers include an
           optional password feature for this, although many security
           packages offer better protection. You should want a screensaver
           for password protection or for entertainment, rather than for
           overhyped 'screensaving' abilities. If you want true
           'screensaving', read the sections below.


         ---- What is Energy Star? Can I use it? (0.0.1)

           The US Energy Star programme is leading to the demise of the
           screensaver as unused monitors power themselves down. Running a
           screensaver, other than an Energy Star (ES) saver on an
           ES-complaint setup, or a backlight dimmer on an LCD, will not
           significantly decrease your screen's energy consumption.

           A completely black screensaver reduces power consumption on a
           standard non-ES monitor by only 23% [Byte, Jan 1994, p204] and
           probably by less on the single-gun Trinitrons more common in the
           Mac world, whereas consumption is reduced by over 90% with an ES
           monitor, and by 100% by pressing the 'off' switch. A 'normal'
           animated pattern, fishtank or cartoon screensaver will not
           decrease CRT energy consumption.

           On a non-ES setup, simply turn your monitor off when you're not
           using the Mac for some time. It's more convenient than going
           through lengthy shutdown and startup processes, saves energy, and
           protects your phosphor better than even a black-screen
           screensaver will. Remember that a conventional monitor uses far
           more energy than the Mac itself does.

           If you use a Quadra, Centris, PowerBook with video-out, LCIII or
           later, or Performa equivalent of one of these models, AND use an
           Energy Star-compliant monitor (look for the star logo) off
           internal video on one of these Macs, you no longer need a
           screensaver. Apple's freely-available 'Monitor Energy Saver'
           package enables the Energy Star features of your monitor with
           these Macs. Your monitor will power down in stages when the Mac
           is on but not in use, saving on your electricity bills as well as
           saving your screen.

           'Monitor Energy Saver' (also known by its codename 'DarkStar') is
           rather hard for netters to find. It's available on AppleLink, in
           the following path:
                           Apple Products
                              Apple SW Updates
                                 Macintosh
                                  Supplemental System Software
                                   Monitor Energy Software (1.0)

           I'm told it's on AOL in the System Software area - do a search
           for 'star'. It appeared as info-mac/cfg/monitor-energy-saver.hqx,
           but was then removed from sumex as a breach of copyright. It may
           still be on some of the smaller info-mac mirrors. It really ought
           to be on ftp.apple.com, but wasn't, the last time I looked. Or ask
           your Apple dealer for it.

           Some Monitor Energy Saver users have reported problems with
           crashing on wake from sleep, which may go to explain why it is not
           widely available. If you have tracked down a conflict, please let
           me know.

           Speculation suggests that the Energy Saver was produced solely to
           meet ES requirements for Apple's US government contract, and that
           Apple has no intention of destroying the screensaver market by
           actively promoting it and making it widely available. It would be
           logical to assume it would be included as part of the expected
           System 7.5 release later this year, perhaps integrated with the
           'Screen' control panel, thus putting this rumour to rest, but I
           have no confirmation of my wishful thinking.

           To see if your setup is ES-compliant, install the Energy Saver,
           set it to fifteen minutes, restart, and leave your Mac for an
           half an hour or so. If on sleep you hear a degaussing noise, or
           on wake the picture takes some time to return to life while your
           Mac beeps, your setup is ES-compliant, and you can remove all
           other screensavers. If the picture returns instantly after a long
           sleep, and your Mac *then* beeps, the Energy Saver won't save you
           energy with your monitor, and you can use a normal 'blank'
           screensaver without feeling guilty. After all, that beeping is
           annoying.

           The Apple AudioVision 14" monitor is reported to be ES-compliant,
           as is newer production of other Apple monitors - look on the back
           to check.

           ES works by disabling the signals on the horizontal and vertical
           sync lines, on Macs that are capable of switching this. An ES
           monitor detects this, and enters one of a series of low-power
           modes; a non-ES monitor loses the picture, and goes black. (BS
           tells me that a special version of AD with an ES-like function
           called 'Ecologic' is shipped with Nanao monitors.)


         ---- What does the 'Screen' control panel do? (0.0.2)

           If you are using a Mac with an internal colour CRT, such as the
           Color Classic or LC5xx, which follow Energy Star recommendations,
           you should be using the Screen control panel supplied with the
           System Software to automatically turn off the monitor circuitry
           when the Mac is not in use - you DO NOT need a screensaver to
           save your screen.

           Unlike Brightness, which works from anywhere, the Screen control
           panel must be in the Control Panels folder at startup to work
           properly. If you want to put Screen somewhere more convenient,
           use an alias.


         ---- Does my PowerBook need a screensaver? (0.0.3)

           No. If you own a Mac with an LCD display you are unlikely to need
           a conventional screensaver, as you already have sleep mode. The
           only 'screensaver' you would be interested in is one that dims
           the backlight after a period of inactivity, to save power when
           running off the batteries while doing long computations -
           included in many PowerBook-specific utility packages. LCDs can
           retain the colour they are set to, whether black or white, in a
           'memory effect' that takes time to change, but does fade away. If
           you use a (probably unnecessary) screensaver, it has been
           suggested that it should be one which flips all of the pixels
           regularly, to prevent this memory effect. This is unrelated to
           the ni-cad battery 'memory effect'. More information on both of
           these topics can be found in the PowerBook FAQs of the Mac
           newsgroups. Read through comp.sys.mac.portables.

           If you are using a monitor connected to your Dock's or
           PowerBook's external video, you should be able to use the Energy
           Saver. Read (0.0.1).


         ---- Can I spin my desktop Mac's hard disk down? (0.0.4)

           You may also want to consider saving even more energy and keeping
           your desktop Mac quiet by spinning down your hard disks when they
           are not in use - PowerBook System Software does this all the time
           to save on battery power. Although some drivers, such as
           Silverlining, include this feature, the standard Apple driver
           doesn't.

           FAQ alert!  Look at SCSISaver 1.2, by Darrell Pfeifer
           <[e-mail]>, on umich in system.extensions/cdevs,
           which adds this ability to drives that support the SCSI 'stop'
           command. If you're using your Mac for filesharing, doing lots of
           intermittent disk access with something like AutoDoubler or
           DiskExpress, or insist on a new, randomly-chosen, AD module every
           few minutes, this will be of no use to you, and you'll find the
           many pauses as the disk spins back up irritating. If your Mac is
           on but idle, with no disk access, for long periods of time, you
           may find the silence a relief.

           With AutoDoubler 2.0x, setting 999 minutes and using the
           'compress corner' on leaving your Mac will help prevent
           intermittent disk activity.


         ---- What screensavers can I use under A/UX? (0.0.5)

           A/UX users will want to use something to cover the login screen.
           So far Moire has been reported as the only screensaver doing
           this. DS and other startup applications will never do this. Read
           through comp.unix.aux for more information on this and other A/UX
           issues.



      -- WHAT MAC SCREENSAVERS ARE AVAILABLE? (0.1)

           Far too many. This FAQ concentrates on AD because it is the most
           popular, is well-established (it has been around for years), has
           the most support from other programmers in the form of different
           screensaver 'modules', and because there are many other packages
           that can run AD modules. It's a standard. AD is commercial and
           costs money, although updates, bug fixes, programming information
           and third-party shareware modules are freely available online.

           If you simply want to play the many shareware/freeware AD modules
           available from ftp sites, download the freeware DarkSide 4.1 -
           see below. As AD, Pyro!, NowFun! and other commercial packages
           *are* commercial, they and their commercial modules CANNOT, and
           SHOULD NOT, be obtained from ftp sites. Updaters can be obtained
           by ftp, but they must update the original package which you have
           bought. If you want to use AD (or Pyro!, or NowFun!, or another
           commercial package) or the modules supplied with it, you must buy
           that package.

           If you are looking for a screensaver, it is well worth obtaining
           freeware and shareware savers, both DarkSide and the standalones
           listed below, from ftp sites and evaluating them before
           considering commercial products. Look in info-mac/gui, or on
           umich in util/screensaver.

           But first, have you read (0.0)? You may not even *need* a
           screensaver with your particular Mac setup.


         ---- Modular screensavers (0.1.1)

           This list is split into the screensaver packages I've seen,
           and the ones I haven't. I make no claims for the completeness of
           this list - everyone and his grandmother appears to have written
           an AD-compatible screensaver, and I can't keep track. Corrections
           welcome.

           If I haven't seen a package, I won't be able to diagnose problems
           with it. You're on your own. Some packages are apparently more
           AD-compatible than others, but I'm not able to rate this on the
           indirect information available to me.

           Modular screensavers, most of which are AD-compatible, with a
           number of different effects supplied in separate files, or
           'modules', include:

         Seen by me:
           After Dark (AD) - commercial, from BS <[e-mail]>
           The most popular. Has the most modules available, and many
           third-party savers can run these modules. Includes the
           screensaver, modules and programming information.
           More After Dark (MAD) is an add-on package from BS that does not
           include the screensaver itself - just more modules and an updater
           for the screensaver.
           Star Trek - the Screensaver (ST), also from BS, includes the ST
           saver and modules, but not the programming information included
           in AD.
           Note that 'for legal and technical reasons' the ST modules
           require AD 2.0x, and DC modules require the player included with
           DC. DS and other AD-compatibles can't see or play these modules.
           You need to use the player BS provides in the package.

          DarkSide of the Mac 4.1 (DS) - freeware, by Tom Dowdy
          <[e-mail]>.
           Also plays AD modules, unlike DS 3.2 and earlier. Like AD, DS
           includes a password feature and a Randomizer. DS runs as a
           startup application under System 7. It only patches one trap when
           it needs to. As it's an application you can quit it at any time
           if you need more memory, and restart it later.
           (System 6 users require DS v2.5.).
           Some of the forty-odd supplied DS-only modules, e.g. Circuit,
           LostInSpace and VaseDance, are very polished, original and well
           worth a look. Many others, e.g. Searchlight and Worms, are
           similar to AD's and Pyro's, but with fewer cute frills.
           An up-to-date DS package is on ftp.apple.com (directory:
           /dts/mac/hacks). A copy is in the info-mac/gui directory.
           A number of people have posted, saying that they own AD and MAD,
           but that they prefer to use DS to run their modules.
           DS 4.1 uses less memory than AD does to play AD modules, and
           takes up less disk space and less CPU time. It is claimed to run
           all AD modules, with the known exceptions of the commercial BS ST
           and DC modules and the SS AD module (version 2.0.1) supplied with
           SS 3.0.
           [Known DS problems:
           If DS stays at the front on startup, even though you checked
           'Finder to front on startup', look at your Startup Items folder.
           DS should be there only once.
           To randomize a selection of DS modules, put them or their aliases
           together in a folder, and open that folder with Open...
           DarkSide's password dialog can crash as a result of extension
           conflicts. One known culprit is Okey Dokey 1.0.1. Try turning off
           Okey Dokey's countdown timer. Both Dan Walkowski and Tom Dowdy
           are aware of this problem. Applescript has also been reported as
           causing problems.
           If DS still crashes, try giving it slightly more memory (your
           INITs may be eating up a lot of program heap space) or trashing
           the DS Preferences file, and see if matters improve.
           The MAD Confetti Factory module crashes under DS 4.0. Get DS 4.1.
           DS's Spectrum module, like other sampling software, is
           incompatible with Global Village's Teleport menu.
           If you keep your AD and DS modules together, note they both have
           'Clock' and 'Puzzle' modules, and that MAD also has a 'Rain'
           module. Remove or rename one of each.
           The manual in MacWrite Pro format. Eventually, an XTND
           translator for this should appear. One in the package would be
           nice. If you want a printed manual, register your copy of
           DarkSide.]
           If you don't already have a screensaver, want to write
           screensaver modules, or are interested in using the wide range of
           free/shareware AD modules, this is *the* screensaver to get. The
           price is unbeatable.

          Intermission 1.0 - commercial, by ICOM Simulations
          <[e-mail]>
           However, ICOM (now Viacom New Media) will direct you to Delrina,
           who have bought the rights to Intermission and use it as the
           screensaver engine in Opus 'n Bill (below). As far as I can tell,
           Intermission has no future - look at Opus 'n Bill instead.
           Intermission comes as an extension, controlled by a desk
           accessory. Plays AD and Pyro! modules, as well as coming with
           over fifty modules in its own format - programming information
           for this included. Its own modules include all the usual - fish,
           worms, spotlights, patterns - as well as originals like Dancing
           Pig, Dragon Kites, and versions of Breakout and Pong. Can't
           display non-text AD About boxes. Has a complicated, Windows-like
           interface with far too many configuration options. Includes
           password and systemIQ features, but passwording and sound were
           unreliable in the copy I tested.
           Put an alias to the Intermission Modules folder in your System
           Folder, and put aliases to your Pyro! and AD Files folders within
           the Intermission folder.

          Screensavor 3.01 (SS) - Commercial, by MIFP Development
          <mbg3b2![e-mail]> or <[e-mail]>.
           A 'specialist' picture displayer. Includes a startup application
           (similar to DS) and an equivalent module (v2.0.1) that will run
           under AD or Intermission - the module is unreliable under DS,
           judging from the evaluation copy of 3.0 MIFP sent me to try out.
           22 sets of pictures (e.g. landscapes, kittens, the planets,
           aircraft, golf courses) also available. Does fades, zooms, and
           many other effects. Shows QT JPEGs and PICTs as well as its
           proprietary format - *far* more flexible than the AD Slide Show
           module. QT required and included.
           A demo of the SS AD module (v1.01) is in info-mac/gui/ad, and
           includes sample pictures.

          Twilight Zone (TZ) - an entry for MacHack 1993 by Steve
          Falkenburg (no email address known).
           Although it isn't a screensaver, this little application will run
           AfterDark modules inside individual windows. The modules can be
           resized, moved, run in the background, and more than one can be
           run at once. It won't run all of the Berkeley Systems modules -
           it crashes on most - but, as an example, I had Fractals, Mathos
           and Spinning Bow Tie running at the same time, faster than they
           do when screensaving. A copy can be ftp'ed from umich (directory:
           util/screensaver/afterdark). It's an unstable and buggy hack, and
           needs work - anyone want to use the source code (included) or
           know where to email feedback?


         Not seen by me:
          Citadel 1.2 - commercial, by Datawatch.
           A security package reported as including hard disk and partition
           locking, passwording, file encryption and destruction as well as
           an AD-compatible screensaver. I haven't seen a copy of Citadel,
           and cannot comment on something I haven't seen - tips welcomed. I
           know nothing further.

          Disney Collection (DC) - commercial, from BS
          <[e-mail]>.
           Like ST, includes its own AD control panel. Like ST, AD
           compatibles can't play this new module format. See TidBITS #192
           for a review. I haven't seen a copy of DC, and cannot comment on
           something I haven't seen - tips welcomed. I know nothing further.
           BS has just launched Marvel Comics Screen Posters, a
           screensaver/desktop-picture package featuring American cartoon
           characters. I know nothing further.

          NowFun! - commercial, from Now Software <[e-mail]>.
           This 'fun' compilation package is reported as including
           FunScreenSavers, an AD-compatible screensaver with thirty modules
           (many previously shareware), FunPictures (an updated DeskPict),
           FunCursors, FunColors and FunSounds (an updated SndControl). I
           haven't seen a copy of NowFun!, but I've been told by others
           which (many previously shareware) modules it contains, and can
           pass this information on to those interested. Email me for
           further details on NowFun! I make no claims for the accuracy of
           this information.
           An updater to take NowFun! to 1.0.1 is available in info-mac/gui
           and on umich as /mac/misc/update/nowfun1.01update.sit.hqx.
           I'm told that NowFun's modules work fine individually under AD,
           with the exceptions of MultipleScreenSavers, Projector, and
           Sports!
           I know nothing further, since I haven't seen NowFun!

          Opus 'n Bill - commercial, by Delrina.
           Uses the Intermission screensaver engine mentioned above, so
           should be able to also run AD and Pyro! modules. I'm told that it
           comes with 16 modules and includes an update service, which you
           pay extra to subscribe to, to receive five new modules every
           quarter. (As Intermission included over 50 modules, I speculate
           that the update service is the original Intermission modules
           repackaged. More information welcome.) Notable for the lawsuit BS
           won in San Francisco against Delrina for infringing BS's 'Flying
           Toasters' design within the screensaver domain. Delrina's
           toasters now have propellers, not wings.
           I know nothing further, since I haven't seen Opus 'n Bill.

          Pyro! 4.1 - commercial.
           This was the original 'fireworks' screensaver, and now comes with
           35 modules. The modules are similar in function to the DS and AD
           modules, although they lack sound. One or two third-party modules
           do exist, but nowhere near the sheer volume AD has - and, unlike
           the others listed here, Pyro! cannot play AD modules. DiskLock
           1.2 is reported as being a commercial security program, with
           similar features to Citadel, that also runs Pyro! modules. I
           haven't seen a copy of Pyro! 4.1 or of DiskLock, and cannot
           comment on anything I haven't seen - tips welcomed. I know
           nothing further.

          UnderWare - commercial, by Bit Jugglers <[e-mail]>.
           Includes an AD-module player, but its main component is an
           animated desktop that interacts with your icons and windows. See
           TidBITS #192 for a review.
           I'm told that UnderWare is incompatible with CopyDoublerand
           CopyDoubler Lite, but only in 24-bit addressing mode. Although
           the CopyDoubler 2.0.2 updater says this is fixed, upgrade to
           2.0.3.
           UnderWare is also incompatible with locking down the menubar when
           panning on E-Machines control panels. Turn that option off if you
           use both.
           I haven't yet seen a copy of UnderWare, and know nothing further.


          There are also two book/disk packages containing just AD modules:
           'Art of Darkness', author Erfert Fenton, Peachpit Press, ISBN
           1-56609-012-1. Ten modules from BS, eight unavailable elsewhere.

           'Cool Mac After Dark', author Ross Scott Rubin, Hayden Books,
           ISBN 0-672-48529-X. Seventeen previously-shareware modules.

           I haven't seen either of these, but I've been told by others what
           modules they contain, and can pass this information on to those
           interested. Email me for further details on the contents of these
           books. I make no claims for the accuracy of this information.

           A third book/disk package of AD modules is under development. See
           (0.2.2).


         ---- Standalone screensavers (0.1.2)

           There are also a large number of small standalone screensavers to
           choose from, and many are present in info-mac/gui. Some of these
           aim to be as simple, small and unobtrusive as possible, e.g.
           TinySaver 3.1, FadetoBlack, BasicBlack. Popular choices include
           Eclipse 2.1 and Moire 4.0.1. MacPassword, elsewhere on info-mac,
           includes Moire for screensaving.

           If you do think you need a screensaver, look at what's freely
           available from the ftp sites first - particularly DS if you're
           running System 7 or better. You are sure to find something to
           suit you.

           There are a number of screensavers for Macs that support use of
           the Brightness control panel and dim an unused screen, e.g.
           Twilight. Twilight 7.1.4 onwards also 'dims' the same way on all
           other Macs, by allowing you to install the Brightness driver. The
           Brightness control panel can then be used on these Macs as well.

           [If you want software brightness control, but don't want to
           install the system software driver supplied for Twilight, a copy
           of the 7.0b1 Brightness control panel, which works on all Macs,
           can be found on info-mac in cp - someone has added new icon and
           version resources.
           Using this when you can just turn your monitor down is
           unnecessary.]

           Microsoft Word 5.1 includes a simple menu-activated screen saver.
           Add 'Screen Test' to the Work menu using Commands to get ready
           access to it when a document is open. Clicking brings up an
           options box.



      -- HOW DO I WRITE SCREENSAVER MODULES? (0.2)

           See (8.0) for ideas that haven't been implemented as modules yet.
           Please don't reinvent the wheel by doing yet another scrolling
           message, spotlight or sliding tiles module. Give yourself a
           challenge!


         ---- How do I write DarkSide modules? (0.2.1)

           If you don't own After Dark or one of the other commercial
           packages, but you have a neat idea for a screensaver and don't
           fancy writing an entire standalone package, look at DS 4.1. All
           the information and code you need to write DS modules is supplied
           within the complete package - for free. I know of only two
           authors who have so far produced a total of four third-party DS
           modules - there's definitely a shareware market window here. See
           the module programming list, below, or address your questions to
           DarkSide's author, Tom Dowdy <[e-mail]>.


         ---- How do I write After Dark modules? (0.2.2)

           You learn to write After Dark modules by examining the example
           code that came with the AD package you bought. This example code
           makes up the Bouncing Ball module. ST does not include
           programming information - BS has posted the programming examples
           and information on AOL, AppleLink, and CompuServe. It's available
           as:
              info-mac/dev/ad-programmers-pckg.hqx
           and on umich as:
              development/source/afterdarkprogramming.cpt.hqx
           This package is also available upon request from BS.

           Although some shareware modules do come with source code, it's
           likely to be out of date. Get the latest version of the AD
           package for up-to-date code. If the last version of the code you
           have came with a version of AD earlier than 2.0x, you're building
           modules with obsolete code. Upgrade!

           There's an AD module programming list, where you can get feedback
           on your work and discuss problems. This list also deals with DS
           modules. Sample code, such as how to animate your module's About
           box, can be obtained from an ftp site - more details can be
           obtained by joining the list. Email:
              [e-mail]
           to be put on the list, and send announcements for it to:
              [e-mail].

           If you are writing AD modules, you will want to make sure that
           they will also run without problems (either coding or cosmetic)
           under the freeware DS 4.1, as well as NowFun!, UnderWare and the
           other commercial AD-compatibles. There's no sense in restricting
           your market or in giving yourself tech-support headaches.



         ---- What can I get for writing a cool module? (0.2.3)

           An AD module book/disk package is under development. It aims to
           include general advice on screensavers drawn from this FAQ, a
           guide to programming AD modules with hints, tips and sample code,
           and a number of never-before-seen AD modules. If you can write
           good AD modules, contact David Zwiefelhofer <[e-mail]>
           for more information.

           As an incentive to write AD modules, you can enter programming
           contests - this is why AD dominates. The 1993 contest closed last
           July. That contest had a grand prize of $10,000, with runner-up
           prizes of hardware, for the best AD modules in Mac, Windows, and
           Computer Artist categories. The best Mac module winner, Steve
           Henck, picked up a 2Gb drive for his 'Possessed' module. Email BS
           for details of the next contest.

           The first contest led to the creation of the MAD package - all
           modules written by AD users. Since then, BS has done little with
           the modules it has garnered from the contests. Perhaps BS can
           make more money from film tie-ins than from selling packages of
           original modules. If you want others to see your modules,
           consider the book/disk package mentioned above.



         ---- Writing your own screensaver (0.2.4)

           Why bother? If you write a module for AD or DS you will have a
           much larger market than for yet another stand-alone screensaver,
           and all the stand-alone niches (smallest, brightness, clock etc)
           have already been filled. You won't have to worry about
           incompatibilities with other software or breaking with the next
           system release - that's the job of the AD or DS authors. And you
           can enter the contests. No-one needs another standalone
           screensaver.

           If you want to write something that does interesting things with
           After Dark modules, the code supplied with Twilight Zone should
           be your starting point. If you really want to write your own
           screensaver, The Macintosh C Programming Primer (Vol 1, 2nd ed.)
           contains source code, as does The Macintosh Pascal Programming
           Primer.

           After Dark defines a gestalt for screensaving that many other
           screensavers and applications now use. Implementing support for
           this is a *very* good idea - ask the programming list for
           information.



      -- HOW CAN I SAVE MY SCREENSAVER PICTURES? (0.3)

           This is short and simple, so it's here. First, have you tried the
           obvious - pressing command-shift-3? This is the 'Camera' function
           key (FKEY), which captures your screen to disk. [Under System 6,
           this only works in black-and-white. If you're still using S6 on a
           colour Mac (why?), skip ahead to Flash-It!].

           Disable your screensaver password if you use one, and set your
           screensaver going. When ready, press command-shift-3 together.
           You should hear a camera shutter click and your screensaver will
           wake. If this is successful, a PICT file called 'Picture
           <number>' will appear in your hard disk's Finder window.

           Double-click on this to open it with TeachText and see what you
           have captured.
           If it's the screensaver picture, well and good. This method
           appears to work fine with AD 2.0x under S7.1, although it may not
           work for earlier ADs and/or earlier Systems. This doesn't work
           for DS 4 under S7.1, which wakes before the screen capture takes
           place - you will get a picture of your desktop instead.

           FAQ alert! If the Camera FKEY didn't work for you, you need to
           get the shareware Flash-It!, a control panel (v3.0.2 at time of
           writing), from an ftp site - look in info-mac/cp. Drop Flash-It!
           into the 'Control Panels' folder and restart. Choose one of
           Flash-It!'s functions and set the function hotkeys to be
           command-shift-3, replacing the Camera FKEY. Repeat the above
           procedure, and this time you should get your picture.

           FAQ alert! Note that Flash-It! is very flexible, and useful for
           grabbing screenshots with menus down or with the cursor visible.
           The Camera FKEY cannot do this.





   HOW CAN I UPDATE MY COPY OF AFTER DARK? (1.0)

           What version of AD do you own? There are two major revisions.
           When someone mentions they own 'After Dark', you can assume they
           mean version 2, of which there have been a number of minor
           revisions in the past few years, listed below. Version 2.0 was
           released back in August 1990, so version 1 is OLD.



      -- HOW CAN I UPDATE MY COPY OF AFTER DARK v1.x? (1.1)

           An updater to 1.1c is available from sites on the Internet. If
           you are already running 1.1c and wish to upgrade to version 2,
           you can do so by returning your master disk to BS with $15. There
           is NO free updater from version 1 to version 2, and the changes
           are major.

           You may find that version 1.1c fails to work on the
           brand-spanking new Mac* you have just bought, or that it won't
           run modules you've downloaded, which require 2.0x. If so, trash
           it, or upgrade to version 2. Or, if you're running System 7.x,
           download the free DS 4.1, which plays AD modules.

           *Here, even a clapped-out IIci running System 6.0.5 qualifies as
           'brand-spanking new'. Version 1 is *old*.

           Note that AD 2.0x requires System 6.0.4 or later.

           FAQ alert! DART 1.5.3, DiskCopy 4.2 and disk images for system
           software up to 7.0.1 are on ftp.apple.com. Upgrade.




      -- HOW CAN I UPDATE MY COPY OF AFTER DARK v2.x? (1.2)

           An updater to update all the various releases of version 2 to the
           latest revision can always be found in info-mac/gui/ad. The
           latest updater is also on umich as
           /mac/misc/update/afterdark2.0xupdater102.cpt.hqx

           BS issues updaters periodically, in line with new Apple machines
           or System software. The updater generally takes up to a couple of
           weeks from release to reach sumex et al, so be patient if you
           have heard rumours of an updater but can't find it yet. BS's
           Disney Collection incudes AD 2.0y, but a 2.0y updater is not yet
           available.

           Alternatively, if you don't have access to ftp or an email
           file-server, you can return your master disk to BS to have it
           updated for free. (You do own a master disk, don't you?) MAD
           includes a copy of the AD updater, to 2.0u or later, depending on
           when the MAD disk was mastered.

           The updater updates version 2 revisions [NOT version 1 - see
           (1.1)] to the latest revision, currently 2.0x. The 2.0x updater
           updates both the control panel and all of the modules supplied
           with the AD package, making minor updates throughout.

           Note that you want the 2.0x updater v1.02. The first release of
           this updater, without a version number, scrambled the password -
           clear the password and turn off passwording to avoid this. The
           second release, again no version number (tut, tut!), fixed this
           by clearing any stored password. v1.02 is the only updater to
           clear the password, add the longer-than-five-minutes Randomizer
           times mentioned in some of the posts about the new features in
           2.0x, and to fix the -'Fish!' sea-floor showing inverted blocks
           of colour problem- that some users of the earlier updater
           versions experienced, by updating Fish! to v2.01.

           There is no reason not to upgrade. The newer your model of Mac
           and/or System, the newer your copy of AD must be to run
           correctly. If you have a problem and you're not running the
           latest version of AD, don't even bother asking about it UNTIL
           you've updated and seen if that fixes it. Experience is that not
           running an up-to-date After Dark is usually the problem, and the
           reported 'problem' is simply a visible symptom of this, which
           vanishes when AD is updated.

           This FAQ assumes that you have the latest revision of version 2
           (2.0x, updater v1.02, at time of writing).


         ---- After Dark revision history (1.2.1)

           The version history of the updater releases (not detailing the
           numerous minor improvements, bug fixes, or feature additions to
           modules) is:
           2.0 - August 1990 - initial release.
           2.0h - Bug fix relating to using (H)yperCard with AD.
           2.0s - Bug fix of (s)ound code. Last version where the letter
           meant anything, since they had squandered two-thirds of the
           alphabet already.
           [BS didn't make this mistake with the Windows version - after 2.0
           came 2.0a....]
           2.0t - September 1991 - Supports new System 6.0.7 sound code.
           2.0u - June 1991 - First fully System 7.0 compatible release.
           Understands new System Folder layout. Much faster when only the
           Finder is running.
           2.0v - August 1991 - First fully '040-cache compatible release.
           2.0w - September 1992 - First fully System 7.1-compatible
           release. Added 'All' and 'None' buttons to the Randomizer.
           Prevents Randomizer and MultiModule recursively launching each
           other. [Updater 2.0w is unique in only updating the control
           panel, MultiModule and Randomizer, and not other modules.]
           2.0x - February 1993 - new control panel icon, updater clears
           password (first release of updater scrambled it - see above),
           more 'When' options, muting sound via the control key. Slide Show
           (updated to 2.1) now works with QT without crashing. Some
           recognition of aliases of modules. Brings AD and the ST package
           into line with each other feature-wise. AD can now play ST
           modules.
           Longer Randomizer times, but only with v1.0.2 of the updater
           updating a non-2.0x Randomizer (Fish! is updated to 2.01 from a
           previous 2.0x update).

           Note that AD 2.0x requires System 6.0.4 or later.

           DART 1.5.3, DiskCopy 4.2 and disk images for system software
           before 7.1 are on ftp.apple.com. Upgrade.

           *** System 7 Pro users require AD 2.0x or later ***

           [Updater release info from Jim Tso at BS]



      -- HOW CAN I UPDATE MY COPY OF STAR TREK: THE SCREENSAVER? (1.3)

           At time of writing, by applying a revision 2 updater LATER THAN
           2.0w, i.e. 2.0x or later. This will update the control panel and
           modules shared in common with the AD package (Randomizer and
           MultiModule).

           At time of writing, there is no updater for the ST modules. A
           ResEdit template for extracting PICT resources from the ST files
           is available from a number of ftp sites, for use by the
           inquisitive.



      -- HOW CAN I UPDATE MY COPY OF MORE AFTER DARK? (1.4)

           There isn't an updater for these modules, and there are no plans
           for one at present, although I have heard reports of
           incompatibilities between some MAD modules and System 7 Pro.
           There was a minor revision of MAD from 1.0 to 1.0a to fix some
           obscure bugs - this is only available by returning your disk to
           BS. I haven't yet seen this revision.

           The changes in 1.0a are:
           Mowin' Man bug-fix. With some large monitors and video cards,
           Mowing Man could crash if the mower started from the top right of
           the screen.
           Tunnel bug-fix. With some video cards, Tunnel could crash if the
           Round Rectangle setting was used.
           Virex-D was removed from MAD 1.0a as it was no longer up-to-date
           - see (5.2).

           [MAD revision info from Jim Tso at BS]



      -- HOW CAN I UPDATE MY AD MODULES OR OBTAIN NEW MODULES? (1.5)

           If the modules are part of the AD package which you bought, you
           need the updater that also updates the control panel - see (1.2).
           If they are part of the MAD package which you bought, you can
           return your disk to BS to get 1.0a - see (1.4). If they are
           shareware or freeware, look in info-mac/gui/ad or on umich
           (directory: util/screensaver/afterdark) to see if a later version
           has been released. These are also the place to look for new
           modules.

           If you are having problems with a particular third-party module,
           see first if a later version is available from an ftp site like
           info-mac. If not, mail or email the author of the module about
           the problem. Authors do appreciate feedback and fan-mail, if not
           cold hard cash.



      -- HOW CAN I UPDATE MY COPY OF DARKSIDE OF THE MAC? (1.6)

           An up-to-date DS package can be ftp'ed from ftp.apple.com
           (directory: /dts/mac/hacks). A copy should also be in
           info-mac/gui. The Apple site always gets a new release first,
           direct from Tom Dowdy, who works there.



      -- HOW CAN I UPDATE MY COPY OF NOWFUN! ? (1.7)

           An updater to take NowFun! from 1.0 to 1.01 is in info-mac/gui
           and on umich as /mac/misc/update/nowfun1.01update.sit.hqx.
           I don't know what it fixes - I haven't seen NowFun!



      -- HOW CAN I UPDATE MY COPY OF MOIRE? (1.8)

           If you've been using Moire for years, and then move it to a new
           Mac, you will need to update to Moire 4.0.1. It's available in
           info-mac/gui.

           If you find that 'Finder Shortcuts' vanishes from the Finder's
           Balloon Help menu, or that restarts or shutdowns are slow, an old
           copy of Moire is probably the problem. Upgrade to Moire 4.0.1.

           If you are using Moire simply because it also includes a menu-bar
           clock, consider getting the free SuperClock! 4.0.4 control panel,
           which is far better, and another screensaver. Moire is also
           available as an AD module - you can run it under DS 4.1.





   HELP! I'VE FORGOTTEN MY AFTER DARK PASSWORD! HOW CAN I GET
           CONTROL OF MY MAC BACK? (2.0)

           A common problem. If you are using System 7, hold down the shift
           key on restart (press the reset button, or control-command-power
           on newer Macs - don't turn the Mac off and on!) to disable all
           extensions and control panels, including AD. If you are running
           System 6, you will need to startup from a floppy disk instead of
           holding down the shift key. If you have an 'extensions manager'
           installed, use that to disable AD instead. (I suggest Extensions
           Manager 2.01 by Ricardo Batista, an Apple employee. It's a free
           control panel on all the ftp sites.)

           Note that you must fully disable AD. If you don't, the password
           information will be carried over to the fresh control panel as a
           security measure. Simply turning off AD with its on-off switch
           does NOT disable it, and won't do you any good. If you can open
           any copy of the AD control panel, you haven't disabled AD on
           startup, and the password will be carried over.

           Throw away the control panel and replace it with a fresh,
           unopened, copy installed from your master disk. Restart and then
           enter a new password.

           If you have misplaced your AD master disk, you could try grabbing
           a copy of the 2.0x (or later) updater and updating the control
           panel instead of replacing it. 2.0x is the first updater to clear
           the password on updating the control panel - see (1.2).





   WHERE SHOULD I PUT THE 'AFTER DARK FILES' FOLDER? (3.0)

           If AD can't find the modules that are sitting as they should be
           in the 'After Dark files' folder, you probably need to update AD.
           Versions 2.0u and later of AD will recognise the folder in System
           7's Control Panels folder, in the Extensions and System folder,
           and on the Desktop, whereas 2.0t and before expected the AD
           control panel and files folder to be in the same place. (This is
           detailed in the MANUAL that came with the AD PACKAGE that you
           BOUGHT. No 'Can you tell I'm a pirate?' questions, please.)

           If you are using AutoDoubler, you can try putting the AD files
           folder on the Desktop - that's next to your hard disk, OUTSIDE
           all folder windows - so that AutoDoubler can compress it. This
           works well as long as MultiModule and Randomizer are not
           deliberately compressed while in use, and doesn't require an
           alias to the AD files folder within the System Folder. If a
           module then crashes your Mac, you can often find out what module
           it was by looking in the AutoDoubler Temporary Items folder on
           restart, as AutoDoubler put copies of all open compressed files
           there.
           [AutoDoubler 1.0x users should see the comments on the PowerDown
           module in (5.2) as well].



      -- WHY DO MY STAR TREK MODULES SAY THEY ARE 'Out of memory' WHEN
           THE REST PLAY FINE? (3.1)

           This is answered here because, like the 'After Dark Files' folder
           question above, it's a matter of getting the files in the right
           place. The ST modules have a lot of pictures, sounds and features
           in common, and to save space these are provided by a number of
           files in a 'Shared Resources' folder, which, like the modules,
           must be in the 'After Dark Files' folder.

           The Star Trek package installs everything correctly, so this
           really shouldn't be a problem.



      -- WHY DOES A DISNEY MODULE SAY IT IS 'Out of memory'? (3.2)

           Try reducing the number of characters appearing in that module.
           At least, I'm told that that's what the card BS puts in the box
           says. Check out (3.1), too.



      -- WHERE CAN I FIND AN AD MODULE THAT SHOWS PICTURES AT RANDOM?
           (3.3)

           The Slide Show module is part of the commercial AD package from
           BS. It displays pictures chosen at random from a folder. If you
           don't have AD, but you're familiar with QT, just save all your
           pictures as single-frame movies (Print2Pict, a chooser device on
           all the ftp sites, allows you to print to movie, disk, etc. from
           any application) and use one of the free movie-playing modules to
           do the same job as Slide Show. See Movies 'Til Dawn under (5.2).

           Displaying pictures at random is ScreenSavor's sole purpose. See
           its entry under (0.1.1).



      -- WHERE CAN I FIND AN AD MODULE THAT PLAYS PICS FILES? (3.4)

           The PICS Player module is part of the commercial AD package from
           BS. It displays a PICS file - AD includes a simple wireframe cube
           PICS file. More interesting files, such as Rob's Eye's (bloodshot
           rendered eyes) and Santa's Sleigh are available from ftp sites -
           look in info-mac/gui/ad.

           If you don't have AD you can open the PICS file with Simple
           Player, and you will be given the option to turn it into a QT
           movie. The movie will be far more compact, but may require more
           disk access to play back. Use one of the free movie-playing
           modules to do the same job as PICS Player. See Movies 'Til Dawn
           under (5.2).





   MY AFTER DARK CONTROL PANEL AND MODULES HAVE LOST THEIR ICONS!
           HOW DO I GET THEM BACK? (4.0)

           There are a couple of modules floating around that have
           accidentally had their 'bundle bits' set, and you have either
           just obtained one of these modules or just rebuilt your desktop,
           bringing the problem to light.

           The 'bundle bit' of a file tells the Finder that the file has
           icon information the Finder must show. A module with a bundle bit
           set causes its (non-existent) icon information to replace AD's
           correct icon information - hence the 'blank' generic icons you
           are seeing.

           To fix this, you need a utility that will show file flags, such
           as the shareware FileTyper 4.1 (on info-mac and umich) or ResEdit
           2.1.1 (on ftp.apple.com). Go through all your modules, bringing
           up the file flag information (This is the 'Has BNDL' box under
           the 'Get File/Folder' option in ResEdit 2.1.1's File menu) and
           make sure the bundle bit is cleared. If it isn't, clear it and
           save that file. Alternatively, just drop all of your modules on
           FileTyper, clear a bundle bit and 'change all' - a simple drag
           and drop operation. (Check that the AD control panel *does* have
           a bundle bit - if it doesn't, the Finder won't know about its
           icons.)

           Once you have cleared that bundle bit, restart and hold down
           option and command to rebuild your desktop files. If you haven't
           found a set bundle bit, it's possible that something like Norton
           Utilities found and fixed the bundle bit a while back, in which
           case you merely need to rebuild your desktop. You should then see
           the AD icons in all their glory. (AD doesn't have ics resources
           for the modules - although DS and ST do - or for MultiModule
           documents. No, I don't know why!)

           If you have Twilight Zone, the AD control panel will look like a
           blank document and your AD modules will become TZ modules, so
           that double-clicking on a module launches it in a TZ window. If
           you rebuild your desktop, they'll look like TZ documents. This is
           normal behaviour - remove TZ and rebuild the desktop to revert
           everything to standard AD.

           FAQ alert! Other things FileTyper 4.1 is useful for:
           Colour floppy disk icons. Drop a floppy disk onto FileTyper, set
           hasCustomIcon, drag the disk to the trash and then reinsert it.
           You don't need SpeedyFinder or Discolour.

           Fixing colour icons. If your hard disk is showing a blank piece
           of paper as its icon, drop it on FileTyper, clear hasCustomIcon
           and restart to get it back to a white box. Then repaste that icon
           you spent ages designing and kept a backup copy of. If you see
           'The command could not be completed, because it cannot be found'
           when trying to paste an icon on a folder, hasCustomIcon is set
           but the icon file is missing. Clear hasCustomIcon with FileTyper.

           Renaming your hard disk. If you can't rename your hard disk you
           are probably using filesharing, which prevents renaming so that
           the network doesn't get confused. Turn off filesharing to rename
           your hard disk. If filesharing isn't on and you still can't
           rename it, use FileTyper to clear the disk's 'nameLocked or
           isSystem' field, then restart. Disk First Aid 7.2, included as
           part of the Software Update Package 2.0.1 on ftp.apple.com, now
           fixes this, along with vanishing files and other disk-related
           problems.



      -- IN LIST VIEW IN THE FINDER, MY MODULES SAY THEY ARE 'a
           particular module' DOCUMENTS'! WHAT'S UP? (4.1)

           Congratulations on spotting the 'bundle bit' problem early - see
           (4.0). That particular module has (or, in the past, had) its
           'bundle bit' set, and if you were to rebuild your desktop you
           could lose your AD icons. Check the bundle bit, as detailed
           above. If you want 'After Dark document' back, you'll have to
           rebuild your desktop once you've cleared that bundle bit -
           although you may want to check all your other modules for set
           bundle bits first, to save you finding another module with a set
           bundle bit and having to rebuild the desktop files again.





   AFTER DARK CRASHES MY MACHINE! WHAT SHOULD I DO? (5.0)

           Are you sure that your problem is caused by After Dark?
           If you are running the latest version of AD - see (1.0) -
           it's almost certainly an individual module rather than the AD
           control panel itself.

           This section deals with AD modules known to crash AD. AD modules
           known to crash DS, other than these, are given in the DS
           information in (0.1). I don't have the knowledge of other
           AD-compatible screensavers to detail modules known to cause
           problems with them, but not with AD or DS. Use this list and its
           troubleshooting advice as a guide for finding any specific
           problems you may have.

           First, if you are using AD, are you running the latest version of
           AD? If not, try updating a copy with the free updater detailed in
           (1.0), and see if the problem goes away. This is likely to solve
           the 'AD doesn't work at all on my setup!' problem.

           If you are already running the latest version, are you using a
           just-released Mac or just-released System? If so, an update may
           be in the works - just email BS. If not, is the problem with a
           specific module, and can you isolate it by trying out different
           modules? Is SystemIQ enabled? If not, is there a specific reason
           why not? Things generally run better with SystemIQ on, and the
           SystemIQ setting can affect some systems.

           If the problem is with a module written by BS, well and good,
           provided that the module is *not the Randomizer or MultiModule*.
           Email them about it, at [e-mail].

           If the module is from a third party, and you cannot find a later
           version anywhere, email or mail the author of the module about
           the problem.

           If you are having trouble with the Randomizer or MultiModule, you
           need to track the problem down. A large number of third-party
           modules don't work well under these, often causing crashes, and
           giving AD an undeserved reputation for crashing in the process -
           this is analogous to buggy shareware system extensions giving
           Macs a reputation for being crash-prone. Choose the software you
           use carefully. If it causes crashes, avoid it.

           If you ARE NOT running any third-party modules under the
           MultiModule or Randomizer, you can grumble at BS. If you ARE,
           look at the list below to see if the problem has been
           encountered. Look around the net for a later (bug-fixed) version
           of the module. See if writing to the author of the module helps.
           Try out each After Dark module in turn under these so that you
           know EXACTLY what causes the problem.

           When trying out a new AD module, try it as the only module
           selected in the Randomizer, and see how well it behaves. If you
           use the Randomizer a lot, this is an easy way of spotting problem
           modules before they crash your machine and lose you work. Most
           modules that crash under the MultiModule or Randomizer will do so
           immediately they are selected - no waiting around needed.

           To see if any modules you already have cause problems under the
           Randomizer, select the Randomizer module, set the delay to ten
           seconds, select 'in order', select Choose... and press the All
           button to choose All modules. [If you do not see an All button,
           you need to update your copy of AD - see (1.0)]. Close AD, go
           into screensave, and watch to see which modules crash your Mac,
           usually as the module starts. Restart [by control-command-power,
           or the interrupt switch on older Macs - Macsbug will let you
           recover from the crash smoothly, but AD will usually be disabled
           until restart], remove the badly-written module, and repeat until
           there are no crashes. (If you use Have-a-Blast or Off the Air,
           see below.)

           Removing modules that crash your Mac is a very good idea -
           although you may know not to use them under MultiModule or
           Randomizer, other users won't, and you know they'll fiddle with
           the AD settings...

           If you must keep particularly impressive 'bad' modules around, a
           neat trick with AD 2.0x under System 7 is to make aliases of the
           offending modules. Keep the 'bad' modules in another folder, and
           their aliases with the other modules in the AD Files folder. AD
           can then see the aliased modules, but Randomizer and MultiModule
           can't, and crashes are avoided. Until someone 'tidies up' your
           'unnecessary' aliases, of course... removing the bad modules is
           far better.


           [FAQ alert! If your Mac is crash-prone, for whatever reason, you
           should install Macsbug 6.2.2 (except on Centris 610s and other
           FPU-less 68LC040 Macs, which have a special version of Macsbug -
           both are on ftp.apple.com in /dts/mac/tools/macsbug), which will
           allow you to exit from most crashes without needing to restart
           (type 'es'), or to smoothly restart without minutes of
           disk-checking (type 'rs'). Shut down by typing 'g power'. Press
           escape to toggle between the debugger and a screen showing what
           the Mac was doing *before* it crashed. Type 'help' for more info.

           The only downside to Macsbug is that any 'Type x error' will put
           you into Macsbug, needing 'es' to continue, making the Mac less
           idiot-proof. Don't worry - that's just Macsbug doing its job.
           Macsbug is not an extension. It lives loose in the System Folder,
           not in the Extensions folder, and it won't cause extension
           clashes - it just highlights the ones you already have, allowing
           you to work around them.

           If your Mac locks up, invoking Macsbug (by pressing the interrupt
           switch, or command-power on newer Macs) and then typing 'es' can
           save you a lot of trouble.

           With its white screen, Macsbug makes AD Randomizer crashes
           noticeable as soon as they happen. Good for troubleshooting.]


          AND IF THE ABOVE ADVICE IS NOT ENOUGH...
           If you have encountered *specific* problems with a module *not*
           mentioned in this FAQ, please let me know by email (and, if
           possible, include a binhexed copy of the module so I can try it
           out) and I'll update this list for others to share in your
           knowledge. Ditto for updates to the modules here - I'm not
           omniscient, and may have missed a bug-fix or two.

           Please do not email me with a long list of modules you're using
           (many of which are mentioned here already), say vaguely that your
           Mac crashes under Randomizer, and ask for my advice. You won't
           get it - that's what this FAQ is for, and I don't repeat myself.
           Self-help is the key here. Use the information provided here to
           eliminate the source(s) of the crashing detailed in the FAQ. If
           it still crashes, use the troubleshooting information to discover
           when and why it crashes. If you discover something new as a
           result, then email me so that I can let others share your find.



      -- MODULES THAT DON'T WORK UNDER MULTIMODULE OR RANDOMIZER (5.1)

           This list has been compiled from information mostly obtained by
           running AD along with lots of other extensions on single-screen
           internal-video Mac IIsi and LC setups that have run Systems 7.0
           through to 7.1. AD 2.0t to x were used. Although some modules do
           have problems with large or multiple-monitor setups, detailed
           information is lacking, since I can't test for it. Anyone want to
           supply a list of 'problem' modules for unusual multiple/large
           monitor setups? Ditto for modules that may have '040 cache
           problems, or problems with 16- or 24-bit deep screens.

           This list details modules that 'work fine' except when run under
           MultiModule or Randomizer, or both. I started this list when I
           was running Randomizer, randomizing a lot of modules every
           fifteen minutes, in parallel with Dan Walkowski's PowerDown,
           which shuts off an unused Mac, under MultiModule. This caught
           more problem modules than most, and I gradually weeded out the
           sources of crashes. Your mileage may vary, and you may not
           encounter some of these problems on your set-up, particularly if
           you are using a Classic or Plus. These days, I'm running a screen
           blanker along with the SCSISaver and Auto Power On/Off control
           panels. Once my 'After Dark Files' folder grew above 12Mb, I
           decided that I was addicted to screensaver modules, and that I
           needed to go cold turkey. The folder has since grown back to 2Mb
           of modules, for playing with in idle moments.

           Some modules misbehave under MultiModule only under very specific
           conditions - size of allocated area, covered or not, system setup
           - and a list of these is impossible. Troubleshooting MultiModule
           settings is left as an exercise for the reader.

           Modules whose latest versions worked fine when this FAQ began,
           but whose earlier versions didn't, are not listed here, as that
           would entail a full version history report of every AD module
           I've seen - difficult and impossible to complete. Modules that
           have had problems corrected during the history of this FAQ are,
           however, mentioned for completeness, under the heading of the
           latest version known. Go and get it. If the module you are having
           a problem with is not mentioned here, see if a later version is
           available. If not, contact the author of the module about the
           problem, and please let me know, too.


          MULTIMODULE AND RANDOMIZER
           If you use both of these, make sure you have the latest revision
           of AD. Versions earlier than 2.0w would crash if MultiModule
           included Randomizer and Randomizer included MultiModule in their
           selections, whenever the Randomizer tried to run the MultiModule
           which was already running. (Say 'recursion', people.) 2.0w and
           later detect this and add incredibly useful 'All' and 'None'
           buttons to the Randomizer [but still no support for my extended
           keyboard's extra cursor-control keys, unlike the control panel
           itself. Grumble.]


          THIRD-PARTY MODULES WITH RANDOMIZER
           And now, that faulty third-party module list, in alphabetical
           order:

          Balloons - BugByte, Inc, 1991 (no email address given)
           A very large (340K) module, advertising a HyperCard stack on
           tying balloons into knots to make figures, that demonstrates some
           balloon shapes with accompanying sound effects. Does not run
           under Randomizer, claiming that not enough memory is available.
           Does not appear to crash.

          Barney Blaster 1.0.1 - Karl Bunker
          <[e-mail]>
           A dancing pink dinosaur explodes. 1.0.1 is said to fix 1.0's
           crashing on some Macs and in 16-bit depths, but 1.0.1 does not
           allocate enough memory to run under Randomizer, and can crash as
           a result.

          Bat Signal 1.1 - subversive software <[e-mail]>
           A Spotlight-like module, but using the Bat Signal, and with the
           coolest about box yet. There are at least two pre-1.0 versions of
           this module in existence with no version numbers - one of those
           didn't work under Randomizer. Replace with 1.1. Well worth
           seeing, *especially* for the about box. Bat Signal Returns is
           under development.

          Blackboard 1.0 - Mark Malamud and Susan Hautala
          ([e-mail] [e-mail]
           [e-mail])
           Pupil drawing on a chalkboard - either punishment or equations.
           0.9 won't run under Randomizer, claiming not enough memory.
           Doesn't appear to crash. 1.0 is said to work correctly, but is
           only available with the 'Art of Darkness' book/disk package
           mentioned in (0.1.1). Mark said that a shareware 2.0 will be
           released late in 1993; I haven't seen it.

          Cards - Chris Christensen (no email address given)
           Puts playing cards at random places on the screen. Refuses to run
           under Randomizer, claiming 'Bouncing Ball: Sorry, there is not
           enough memory.' (and showing its code origins. At 225K, it's
           obese, too - the Klondike 5.1 game takes under 100K, and you can
           *play* that). Does not appear to crash.

          Chomp! - BS <[e-mail]>
           This was one of the original modules for the original AD. Bites
           are taken out of the screen with a chomping sound. Causes the
           System 7 Finder to quit when run under Randomizer with AD v2 on
           my setups. No longer supported by BS and should probably be
           trashed. Although other modules from the same era, like TacTiles
           and Shapes, seem to work fine for me, treat them with caution.

          EarthSplash 1.1 - Chuan Y. Fu <[e-mail]>
           (Previously Earthbounce 1.0). Unstable under Randomizer - seen to
           crash in _MakeRGBPat. The author claimed he was working on an
           update.

          Faces in the Dark 1.0 - Geoffrey Hutchison (no email address)
           Draws b/w face doodles. Occasionally 'freezes' under Randomizer -
           cmd-opt-esc recovers to Finder.

          Frect 1.0 - Adam Miller <[e-mail]>
           Produces 'fractal rectangles'. Causes the System 7 Finder to quit
           when run under Randomizer.

          Gates Does Windows 1.0.2 - Robert Gibson, Mark Simmons
          ([e-mail], [e-mail])
           Bill Gates appears as a window cleaner. Very large and
           impressive, but 1.0.1 crashed under Randomizer as it runs out of
           memory. Version 1.0.2 fixes this crashing, but behaves oddly on
           some systems under Randomizer. This module is a 'ZiffNet
           exclusive', so it can't be put on ftp sites. You'll have to ask
           someone for it - but not me. I had to do a lot of asking around
           to track this module and its reported problems down, and I'm
           annoyed with ZiffNet as a result.

          Hearts 2.0 - Josh de Cesare <[e-mail]>
           Large (453K), visually impressive module where rendered hearts
           grow, spin and move around the screen. Doesn't appear to allocate
           enough memory under Randomizer, and crashes badly under
           MultiModule. No reply from the author at the address he gives.

          HolisticSofa 0.94 - Alan Keahey ([e-mail] or GEnie:
          A.Keahey)
           This module explores the sofa-on-stairs problem detailed in
           Douglas Adam's 'Dirk Gently's Holistic Detective Agency'. It
           crashes under the Randomizer on most newer Macs. The author wrote
           it on a Plus, which it didn't crash on, and can't duplicate the
           problem. Another Plus owner has reported crashing under
           Randomizer.
           [Also available as a standalone screensaver.]

          Kablooie 1.0 - Adam Miller and Jakub Buchowski
          <[e-mail]>
           A customisable fireworks module for AD - just what it needs to
           get one over on Pyro!'s main selling point [DS and Intermission
           include fireworks modules]. Puts up 'Kablooie:' running under the
           Randomizer and nothing else. Adam Miller knows of the problem,
           but no fix has appeared.

          Kings Cross Coke 1.0 - John Rotenstein (PO Box 165, Double Bay
          NSW 2028, Australia)
           Shows logos and illuminates them as if they were flashing/cycling
           neon signs. Includes a scrapbook feature to choose images from.
           Has memory problems - crashes under Randomizer and MultiModule,
           and is pretty flaky on its own, especially when cutting and
           pasting in the scrapbook. Spectacular, but risky.
           [Also available as a stand-alone application (v2.0) in
           info-mac/grf]

          Millions of Colors 0.5 - Guy Rice (Mark Hatle,
          [e-mail])
           Bands of colour. Doesn't work under MultiModule. Email will be
           passed on by Mark Hatle. Package includes source code - anyone
           want to fix it?

          Nebulae 1.0 - Bryan & Lisa Gibson-Winge (Compuserve: 72677,3222)
           Complains of not enough memory to run under MultiModule or
           Randomizer. Doesn't appear to crash.

          Off The Air 1.0 - Guy Rice (Mark Hatle,
          [e-mail])
           Simulates a noisy television channel after the station has gone
           off air. Under Randomizer changing modules every few minutes,
           causes a crash a few modules AFTER it has run. (Trashing memory?
           Finding this one took ages.) The 'Set Monitor Depth' feature is
           bad ju-ju and can also crash the Mac. Email will be passed on by
           Mark Hatle.

          Punkin Patch - Steve Henck <[e-mail]>
           A 'Halloween' module. Cute graphics. Won't run under Randomizer,
           claiming not enough memory for off-screen graphics. Doesn't
           appear to crash.

          Rrrring! - Steve Henck <[e-mail]>
           Assorted deaths to ringing telephones. Cute graphics. Won't run
           under Randomizer, putting up 'Randomizer:'. Doesn't appear to
           crash. Included in the 'Cool Mac After Dark' book/disk package
           mentioned in (0.1.1).

          Shredded Crystals - BS <[e-mail]>
           This was one of the original modules for the original AD. Jagged
           shapes appear on screen. Causes the System 7 Finder to quit when
           run under Randomizer with AD v2 on my setup. No longer supported
           by BS, and should probably be trashed. Although other modules
           from the same era, like TacTiles and Shapes, seem to work fine
           for me, treat them with caution.

          Sierpinski's Gasket 1.1 - David L. Thompson, WinterBright
          Software <[e-mail]>
           The author confirms reports that this can crash under MultiModule
           when running with MAD's Satori. The reason is unknown. I can't
           duplicate this problem.

          Sparkler 1.0 - Mike Wessler
           Pixels explode off the screen. Crashes under Randomizer. [Not to
           be confused with the catherine-wheel-like Sparklers 1.0, by Frank
           Kubin, which works fine under both MultiModule and Randomizer.]

          TerrainMaker 2.0 - Adam Miller and Jakub Buchowski
          <[e-mail]>
           Reported as just saying 'Randomizer:' under Randomizer on an
           unusual video setup - a IIcx with PCPC Nubus card and 19"
           monitor. Appears to work fine on more standard video setups.

          VectorBalls 1.0 - Mark Adams, Maverick Software
          ([e-mail] [e-mail])
           Very impressive bouncing sets of crystal-lattice-like 3D balls.
           Crashes under Randomizer and MultiModule. The author claims the
           crash occurs in a ROM routine he calls, and is not sure why. With
           the crashing fixed, and a 'Random Shapes' option, this module
           would be a must-have.
           Reported as being included in the NowFun! screensaver mentioned
           in (0.1.1) - version unknown.



      -- MODULES WITH OTHER KNOWN PROBLEMS (5.2)

           In alphabetical order:

          Have a Blast 1.0.1 - Alan Goates, Otherware
          <[e-mail]>
           1.0 could crash on wake (moving the mouse or Randomizer choosing
           another module) if 'Repair Damage' was chosen. 1.0.1 fixes this.

          Hopper 1.0.1 - Rob Snevely, Wild Nobility Productions
           Under later versions of AD, this module only displays its
           generated pattern in the bottom-right quadrant of the screen. It
           uses the whole screen under DS, though. Very strange. Anyone have
           an email address for these guys?

          Movies 'til Dawn 1.01 - BS <[e-mail]>
           1.01 works with all versions of QT, unlike 1.0, which stopped
           working at QT 1.5. Get 1.01 and trash 1.0.
           Playing movies is pointless for a screensaver, since it may save
           your screen, but kills your hard disk through overwork and keeps
           your CPU running at full speed - important on a portable. If you
           *must* play movies, make sure you have QT 1.6.1 or later. Far
           less disk access and memory is used than with 1.5 or earlier.
           There's also Movies in the Dark 1.0 by Maurice Volaski and the
           OURA QT (say each letter!) movie player 1.0d2 module by Laurence
           d'Oliveiro. There's a Bouncing Movie module, but it's a quick
           hack that no longer works. Trash it and get one of the others.
           Note that Slide Show 2.1 (with 2.0x or later) can display QT
           JPEG-compressed PICT files, which is far more useful than playing
           movies. Slide Show 2.0 or earlier will hang on the second
           screensave if a QT JPEG is used.
           If you use JPEG pictures with Slide Show 2.1, remember that
           pictures are uncompressed with a blank all-colours-are-black
           screen. AD will not wake until QT has finished decompressing the
           picture, so you may spend time staring at a black screen. If you
           have the password feature enabled, you may have to type the
           password blind, and then wait for QT to finish decompressing the
           picture - a similar problem to using 'FadeAway' down to 0% with
           the password enabled.
           [And you know about QT's 'Startup Movie' feature, right?]

          Orbs Return 2.0.2 - Stephen Linhart <[e-mail]>
           Crashes in 16- and 24-bit colour depths. Version 3.0 is available
           as part of the NowFun! package mentioned in (0.1.1), and does not
           have this problem.

          Paw-Paw 1.3b3 - Aaron Barnet <[e-mail]>
           Version 1.2b had known memory problems, most visible when running
           with Microsoft Excel or Word (like a lot of Mac software - blame
           Microsoft's un-Mac programming methods). Get Paw-Paw 1.3b3 or
           later (in info-mac/gui/ad) which fixes these problems, and trash
           1.2b.

          PowerDown 1.1 - Dan Walkowski <[e-mail]>
           Shuts off an unattended Mac after a pre-set time. Ideal for Macs
           with full 'soft' power on and off.
           DS 4 users can get the same functionality with Fabrizio Oddone's
           DarkShutdown 2.1 DS module, which works nicely with the Shutdown
           Delay 2.0.1 control panel. IIsi, IIvx and Q840av users gain
           additional functionality with the Auto Power On/Off control panel
           first supplied with the av machines. Note that Auto Power is
           incompatible with Network Time.
           Running PowerDown in parallel with Randomizer under MultiModule
           with the AD files folder on the Desktop so that AutoDoubler
           1.0.7i could compress it (whew!) led to extra copies of the
           modules running when PowerDown shuts down being put in an
           AutoDoubler Temporary Items folder. There was no crash or other
           undue behaviour. Telling AutoDoubler not to compress PowerDown,
           Randomizer and MultiModule prevented this from happening -
           AutoDoubler always puts copies of compressed files open at
           shutdown in the Items folder These modules were running at
           shutdown, and weren't closed properly.
           If you are using PowerDown, look at the Okey-Dokey 1.01 control
           panel from the same author, which presses the default button in a
           dialog after a pre-set time. This allows you to have open
           documents in most applications saved automatically on shutdown,
           which would otherwise stop at the first dialog. DarkShutdown
           handles this itself.

          Virex-D (MAD 1.0) - BS <[e-mail]>
           Virex-D, one of the MAD 1.0 modules, was an advertisement for the
           commercial Virex virus-killer. As the D indicates, Virex-D
           DETECTS viruses - it does not remove viruses or repair damage
           caused by viruses. Virex-D has not been updated recently and is
           no longer distributed with MAD 1.0a. It SHOULD NOT be used for
           virus protection. It wears your disk unnecessarily, too.
           FAQ alert! Use the freeware Disinfectant application (version 3.3
           as I write) and Gatekeeper system extension (version 1.3 as I
           write), available from all good Mac ftp sites, to combat Mac
           viruses.
           A commercial package is not a requirement for protection from
           viruses. Remember that the few Mac viruses in existence are
           mostly benign and are very rarely seen - this is not something to
           even think about if you have an up-to-date virus-killer, and
           Disinfectant and Gatekeeper are far more than adequate, not to
           mention completely free. Read the excellent Disinfectant on-line
           help for complete information on Mac viruses.
           If you have access to the World-Wide Web, you can get hold of
           Disinfectant and John Norstad's other Mac software creations with
           the following URL:
              http://www.astro.nwu.edu/lentz/mac/jlnstuff
           Simply click on Gatekeeper's title box to have it launch NCSA
           Mosaic and find Chris Johnson's area of the Web.

          VoiceWaker 1.07 - Alessandro Levi Montalcini <[e-mail]>
           This module works with a microphone to wake up a Mac when you
           shout at it. (A neat trick - just say 'Wake up!' and pretend you
           own a Quadra av :-) All versions seen, including 1.07, crash the
           Mac on screensave if a Global Village Teleport ADB modem is in
           use and the Teleport menu is present - the Teleport menu appears
           to be incompatible with all sampling software. 1.07 is included
           in the NowFun! screensaver. It remains at 1.07 after using the
           NowFun! 1.0->1.01 updater.





   EXTENSION INCOMPATIBILITIES WITH AFTER DARK (6.0)

           There are few extension, INIT or control panel conflicts with AD
           - most problems originate with badly-written AD modules, listed
           above. DS conflicts are listed in (0.1).



      -- KNOWN INCOMPATIBILITIES WITH AFTER DARK (6.1)

           In alphabetical order (well, there are only three I know of):

          Attention 1.02 <[e-mail]>
           This control panel allows you to select a sound other than the
           presently-selected 'beep' sound for notification alerts.
           1.0 prevented AD from sleeping if 'Always Audible' was selected
           and had minor incompatibilities with CarpetBag.
           1.01 and 1.02 fix this, but may cause crashes with the new
           StyleWriter II driver's beep-after-printing feature. Use with
           caution.

          MacWrite Pro (Claris)
           It's reported that AD cannot automatically sleep when any version
           of MacWrite Pro (latest is 1.0v4) has a document open.
           Speculation is that MacWrite Pro is doing background processing
           when not being typed into.
           I'm told that sleep can occur if you use AD's 'sleep' corner, or
           place the pointer on the menu-bar or the document title-bar.

          TouchBase Pro (After Hours Software)
           TouchBase Pro 2.0 won't let After Dark sleep if it is running,
           either in foreground or background. After Hours say that this is
           fixed in 2.0.1.





   MODULE NAME CHANGES AND SIMILARITIES (7.0)

           Over the years, a number of AD modules have changed their names
           to avoid being confused with other products. Also, some modules
           out there have similar names, but are not related. This should
           help clear all that up.



      -- THE NAME HAS CHANGED (7.1)
           Names on the left are old -> changed to names on the right. Look
           out for the new AD modules, and trash the old ones once you've
           got their replacements. Listed in alphabetical order of the old
           names.

          EarthBounce 1.0 -> EarthSplash 1.1
           Has Randomizer problems. See above.

          MacTabloid 2.0 -> Headlines 1.0.1
           MacTabloid 2.0 is a third-party hack of Headlines 1.0.1. The size
           of its word database appears to give it problems Headlines does
           not have. MacTabloid runs out of memory under Randomizer - the
           memory requirements do not appear to have been adjusted upwards
           for the larger database. Avoid it - Headlines 1.0.1 is the
           latest, most stable, official, version.

          Mandelbrot -> Fractals 1.33
           Alessandro Levi Montalcini's 'Mandelbrot' underwent a name change
           when Hoffman and Hartshorne's 'Mandelbrot' module appeared as
           part of the MAD package. It's now the shareware Fractals 1.33,
           and is a full-fledged configurable fractal generator, whereas
           MAD's commercial 'Mandelbrot' just shows you the set and some
           expanded detail. A later version of Fractals, 2.1.2, is reported
           as being included in the NowFun! screensaver.

          Wallpaper 1.0 -> Mathos (no version, Oct. 1, 92 given in about
          box, but released May, 93)
           Generates fractal 'wallpaper' patterns. Name changed to avoid
           confusion with Thought I Could's commercial 'Wallpaper'
           desktop-pattern utility. (I'm a fan of the far cheaper Desktop
           Textures 2.1, on info-mac, and on microlib.cc.utexas.edu as:
              /microlib/mac/app/desktop-textures-21.hqx
           myself.)
           A number of versions of the Wallpaper module were released
           without version numbers and as versions 1.0 - with and without a
           separate coprocessor-only Wallpaper881 module - so upgrading to
           Mathos or Mathos881 (together in one archive) will solve your
           'what version is this?' problem for now.



      -- NOT TO BE CONFUSED (7.2)

           These AD modules have similar names, but are different!

          Lines by Charles Clarke, ArtLines by AC Capehart, LineCA 1.0.1 by
          WildMan Software, Quantum Lines by Scott Berfield and Roaming
          Lines 1.1c by David Bau.
           Lines simply fills the screen with coloured lines, ArtLines adds
           blanking frequency and line thickness controls, LineCA is a
           scrolling one-dimensional Life-like cellular automata generator,
           Quantum Lines is bouncing twisting pattern, and Roaming Lines is
           a variation on Berkeley's String Theory with some neat options.

          Maze (the first version) 1.0 by David Bau, and (Calico) Maze
          1.1.1 by Richard Lesh.
           Two different maze builders/solvers. Bau's Maze lacks colour, but
           has an interesting maze-drawing method. Calico Maze has more
           colour and more choice of maze sizes than the very similar MAD
           Snake module, and is well worth a look as the 'definitive' Maze
           module.

          Messages by BS, and Random Messages 1.0 by Paul Russell.
           Two modules that choose a string from a message-list and display
           it on screen. MAD includes the polished Say What?, but the
           out-and-out-winner has to be Headlines 1.0.1 by Jamie McCarthy,
           which, like the unix spew it's based on, generates hilarious
           random headlines from a topical database.

          Sparkler 1.0 by Mike Wessler, and Sparklers 1.0 by Frank Kubin.
           Sparkler has Randomizer problems. See above. Two totally
           different modules and effects.





   MODULE REQUESTS (8.0)

           Right, this is the part where you send in your neat ideas for
           screensaver modules, in the hope that someone will turn them into
           reality. Requested are:

           A 'Sequencer' module that lets you control the order and timings
           of your AD modules, so that you can have following modules
           perform interesting effects with the stuff left on the screen.
           Randomizer just doesn't cut it - Murphy's Law dictates that
           Puzzle ends up shifting a blank screen around, for example.
           (Intermission includes a basic 'Sequencer' module that does this,
           but it requires Intermission to run.)

           A SoundTracker MOD file player, ideally incorporating graphics
           like DS's Spectrum's. One has been developed, but has not yet
           been released to macgifts. (Tracker/ProTracker-playing code is
           readily available. ST includes a straightforward sound- and
           SoundEdit-file playing module.)

           A screensaver that creates realistic-looking Finder windows with
           icons, and has the mouse pointer doing operations, so that you
           can claim that your Mac is working even when you are not.
           (AppleEvents on a scriptable Finder?) Underware and DC do this
           to some extent, but it's rather obvious that a screensaver is
           running.

           A GIF picture viewer. Slide Show does PICTs and JPEGs (with QT)
           but not GIFs. Aaron Giles <[e-mail]>, the author of
           JPEGView, suggests that all a module need do is send AppleEvents
           to JPEGView to control its SlideShow feature as a screensaver.
           Contact him for details. MIFP, the makers of ScreenSavor, are
           considering adding GIF support if user demand warrants it. What
           the world *really* needs, though, is a GIF translator plug-in for
           QT.

           A 'starfield' module that simulates Doppler shift accurately,
           which neither Star Trek, 'Warp Factor' or 'Warp!' do.

           A neko or gengi-type module featuring puppies, not kittens.

           A 'dancing bear' module.

           Tetris. It runs under everything else...

           Exact copies of the Sun screensavers, so Macs can pretend to be
           workstations.
           Exact copies of the default screensavers supplied with Windows,
           so that Macs can lurk better in PC-dominated offices.

           A module giving filesharing information - who's using your Mac?

           Curtains pulling across the screen.

           More modules featuring domestic appliances. We have Flying
           Toasters, fridges and washing machines (Major Metaphysical
           Appliances, with the Art of Darkness) but no steam irons,
           blenders, tumbler dryers or cats in microwave ovens.

           And fixes to all those still-buggy modules listed above, of
           course. Please...
