- *************************** BUGS ****************************
-
- Oh yeah, in a program of this magnitude, there are bound
- to be some surprises, and not all of them good! Please let
- me know what mistakes and problems you find because I'm
- always working to develop this thing. If you are using the
- shareware version, rest assured that I support registered
- users in these ways: Generally, large bugs have been
- identified and repaired in the registered version. If
- anything major slips through to early registered users, they
- receive free upgrades.
-
- ************************* PROBLEMS **************************
-
- If you have problems, experimentation is the number one
- way out. However, I have compiled a few ideas that may help:
-
- It is rare but possible to lock up your computer with The
- Multimedia Workshop. Simply reboot and try again should this
- happen. As always, your picture file will be saved to the
- most recently drawn element.
-
- Here's a couple of things I haven't yet worked out for
- this version:
-
- * In VGA-Lo mode, fills don't get all the way into corners on
- some shapes. To fill a whole irregular area, you may have to
- select FILL a few times to get all the unfilled corners.
-
- * If creating a presentation in CGA-HI (two-color) mode,
- and if you change the background color, check your colors in
- the finished product because sometimes the background takes
- on the 'background' color and sometimes the foreground color
- changes instead, depending on various computers. You might
- want to try it on a couple of different CGA and VGA-equipped
- machines.
-
- * There are TSR's which are incompatible with any graphics
- program which can change from one graphics mode to another,
- such as The Multimedia Workshop. The one which I found most
- troublesome was one called CLK.COM which puts a little
- digital clock in the upper right corner. It locks up the
- system even though not visible while The Multimedia Workshop
- is running.
-
- * TSR's are often not equipped to pop up properly within
- graphics programs. For instance, even the well-regarded
- SIDEKICK causes funny stuff when popping up in a VGA screen.
- You can simply ignore the effects (random red lines) by
- selecting something from the VIEW menu after using Sidekick
- and similar programs.
-
- * Large fonts are in slightly different proportion when
- displayed in Hercules graphics than in other graphics modes,
- so check Universal Mode presentations on Hercules equipped
- sets if you can.
-
- * Fills are not universal from one graphics mode to another,
- so if creating in Universal Mode, keep fills to a minimum and
- check your presentations on several different computers.
-
- * Printer support is not yet complete. Some types of
- printers will not work. With some other printers, in some
- graphics modes, the aspect ratio of the finished picture is
- out of proportion, meaning circles become ellipses. Also,
- there is not yet support for gray scaling.
-
- In the meantime, a good alternative is to use
- GRAPHICS.COM which comes with MS-DOS. Load GRAPHICS.COM
- before running TMW.EXE or MSHOW.EXE, then press [Shift] and
- [Print Screen] when you want a paper copy.
-
- The Multimedia Workshop is designed to fit within 640k
- RAM along with one or two medium size TSR's, but with less
- RAM or big TSR programs you might have a space problem. If
- you don't have enough space in memory, try dumping your
- TSR's. Many times you have TSR (Terminate Stay Resident)
- programs taking up part of your RAM. They are invoked from
- the AUTOEXEC.BAT file. If you have a pop-up multipurpose
- program such as SIDEKICK, you might have to delete it's call
- from your AUTOEXEC.BAT file. If you are running The
- Multimedia Workshop from within a menu or shell program, and
- have memory space problems, try running it directly from DOS
- without the shell program.
-
- If you have only one 360k floppy disk and no hard disk,
- you can dump the documentation files (*.DOC), and you don't
- need MSHOW.EXE until you are ready to put together a final
- product disk. This will leave quite a bit of room for your
- picture files. You need only keep the .CHR files
- corresponding to fonts you will actually use in your
- presentation.
-
- If you don't have a hard disk, and The Multimedia
- Workshop writes to the disk too slowly to suit your tastes,
- you can create a small RAM disk with RAMDRIVE.SYS, or
- VDISK.SYS which comes with MS-DOS. This will speed up The
- Multimedia Workshop considerably since it will write to a
- picture file stored in RAM and not on a floppy disk, but if
- you lose power or have a lock-up, you'll lose your picture
- file, so back it up to the floppy frequently. Keep the RAM
- disk small, perhaps 64k or so, because The Multimedia
- Workshop needs most of 640k RAM to work properly.
-
- In some multitasking environments, such as MS-Windows,
- it may be possible to juggle enough programs that you end up
- with choppy sound effects. Should this happen, merely exit
- programs you are not actively using or reapportion 100% of
- CPU time to The Multimedia Workshop.
-
- If you install a WAIT FOR USER in your presentations,
- remember that it is there, or you will seemingly lock up your
- system or your end user's system until a key is pressed.
-
- If you have any questions that you cannot answer by
- reading these files, or by experimentation, you can try
- phoning me at 503-846-7884. (or write a letter) I may not
- have much time available for unregistered users, but I'll
- help when I can. Hours are generally 9-5, Weekdays, West
- Coast Time.
-
- I'm also available for consulting. For questions you may
- have beyond general use of this program, such as business or
- programming advice, I will gladly help. The charge for this
- service is $40 per hour, invoiced monthly. There is no
- minimum charge and many questions can be answered within a
- few minutes.
-
- TROUBLESHOOTING CHART
-
- 1. Computer locks up:
-
- a. Have you forgotten about a WAIT FOR USER?
-
- b. Try eliminating TSR programs.
-
- c. Have you edited a picture file with a text editor?
- It is possible to make mistakes which will foul up the
- program. Delete the file, use a backup copy and try
- editing again.
-
- d. Perhaps you have tried to use a .PCX file which is
- incompatible with the current video mode. PCX is a whole
- family of specifications, and some PCX files may be
- entirely incompatible with The Multimedia Workshop.
-
- e. Use of LOOP may be incorrect, or you may have
- forgotten you put a LOOP in a script.
-
- f. In most cases, simply reboot and try again.
-
- 2. Sounds are choppy, animations are clunky:
-
- a. You are probably using a multi-tasking program such as
- MS-Windows. Simply allocate 100% processor time to
- The Multimedia Workshop, and MSHOW.
-
- 3. Picture fills up with one color or pattern.
-
- a. A FILL has gone wild. The border around a filled area
- must be complete and usually of the same color as the
- fill. FILL works differently in 256-COLOR VGA-LO mode.
-
- 4. Picture is squished into a corner of the screen, or
- only a portion of the picture is visible on the screen.
-
- a. This happens when there is confusion about which
- graphics mode is being used. Make sure to use pictures or
- modify libraried pictures to fit the main picture graphics
- mode.
-
- b. If editing a picture file with an ASCII editor, make
- sure the "mode" statement on the very first line of a
- picture file matches the mode you intend to use.
-
- c. You may be trying to use a .PCX file in the wrong
- video mode.
-
- 5. Almost all typefaces look alike.
-
- a. If The Multimedia Workshop cannot find the external
- typeface files, *.CHR, all but the TRIPLEX typeface will
- look like BITMAP typeface. The appropriate .CHR file(s)
- for the typeface(s) in your presentation must accompany
- your files on disk. More important, MSHOW.EXE must also
- have access to the .CHR files when required to present
- typefaces you have put into your presentations.
- Otherwise, the text you have used in your pictures may be
- wildly out of proportion.
-
- 6. Colors are all goofy.
-
- a. You have imported a .PCX file which automatically
- changes the color palette. If necessary, you can manually
- change it back with CHANGE PALETTE COLORS, in the
- OPTION menu.
-
- b. After manually changing the color palette or hooking a
- .PCX file, you may have to select FORCE POINTER TO WHITE,
- in the OPTION menu so that you can see the mouse pointer
- and on-screen help, etc. If changed back to white, the
- corresponding parts of the picture will also be changed
- to white. (Note: You can always delete the FORCE
- POINTER TO WHITE with a text editor in the picture file,
- when done building the picture file.)
-
- 7. All other problems:
-
- a. Try again.
-
- b. Think.
-
- c. Always make backups.
-
- d. Ask a friend who enjoys computer challenges.
-
- d. Phone me: 1-503-846-7884 (I'm not always available, but
- you can try.)
