*************************** 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 improve 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 SEE from the control panel 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.
* If FASTMODE is selected, there is a glitch in which the
control panel remains on the screen when you should be
working on your picture. This happens quite rarely. When it
does, simply select SEE from the control panel, then resume
with your work.
* The PAPER option is provided as as afterthought. Printers
are not fully supported, yet. A few won't work at all, and
some others give you a goofy aspect ratio in some graphics
modes. Also, there is no gray scaling. If you are not
getting good results, you might try using GRAPHICS.COM which
is a TSR that comes with MS-DOS. To use it, type GRAPHICS at
your DOS prompt before you start MW.EXE or MSHOW.EXE. Then
press [Shift] + [Print Screen] to make 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 your
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, of
course you can dump the documentation files (*.DOC), but you
can also dump all the help files. Without the help files,
when you call for help from the control panel with a click of
the [Esc] key or the right mouse button, you'll get a
harmless notice that the help files are missing. 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.
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 try to help when I
can. Hours are generally 9-5, Weekdays, West Coast Time.
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. 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 TRIP 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 COLOR PALETTE, in the DOOR
option of the control panel.
b. After manually changing the color palette or hooking a
.PCX file, you may have to select FORCE POINTER TO WHITE,
in the DOOR option on the control panel 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. Output to PAPER is not correct:
a. Try using GRAPHICS.COM, which comes with MS-DOS, to
make paper copies.
8. All other problems:
a. Try again.
b. Think.
c. Always make backups.
d. Phone me: 1-503-846-7884 (I'm not always available, but
you can try.)
