I wonder whether anyone recognises the following problem and can suggest
a solution. I have just installed MPLAB 3.10.03 under Windows 3.1 and I
find that it crashes my PC every time I run it. Unfortunately, I have
not previously used MPLAB and so I cannot say whether this is a problem
with other versions. However, MPASM for Windows in the same package
runs fine.
The specific symptoms on double-clicking the MPLAB icon are that the
hourglass appears, the hard disk is accessed in several bursts of a few
seconds and then continuously. Nothing further seems to happen. At
this point, the mouse is still able to move the hourglass around but the
system appears otherwise dead (e.g. "Caps Lock" and "Num Lock" no longer
toggle the LEDs on the keyboard). CTRL-ALT-DEL does not produce the
usual Windows response (e.g. "The application has stopped responding to
the system") but instead fills the screen with garbage and a system
reset appears to be the only option.
Before anyone asks, I have deleted all copies of BWCC.DLL other than the
one in the MPLAB directory (confirmed by BWCCFIX.EXE).
Now I know there are plenty of people out there who have MPLAB working
happily. I tend to blame my system, but I haven't had this type of
major problem with any other Windows software (I assume that the odd
non-reproducible General Protection Fault is not untypical).
I'd appreciate any helpful suggestions.

Ian,
3.10.03 is an interim release of MPLAB and it was found to exhibit the
symptoms you describe on some PC's. Get the latest version v3.12 and
you should be able to run just fine.

Thanks for your speedy response. I tried downloading and installing the
latest version today (MPL31200) but unfortunately MPLAB still fails with
exactly the same symptoms. I had previously emptied my MPLAB directory
to make sure that no residue was carried across from v3.10 (although I
can't vouch for other directories). I have also double-checked that no
rogue copies of BWCC.DLL are lurking.
For your information, only Program Manager is running before MPLAB fails
to start. To recap, the precise order of events is: on double-clicking
the MPLAB icon, the hourglass appears and the hard disk is accessed a
few times, then all of the Program Manager icons disappear, then the
hard disk is accessed continuously and the keyboard appears to lock up
(Caps Lock and Num Lock don't work). Nothing further seems to happen,
and CTRL-ALT-DEL fills the screen with repetitive garbage (white blocks
and strange characters).
I'd appreciate any further thoughts. Thanks in advance.

I guess we need to back up then and find out more about your system.
How much memory/disk space do you have? What kind of CPU? You're using
Windows 3.1 by itself (not running under some other operating system
like). MPLAB needs a 386 or greater, about 4M of RAM, a few megs of
free disk space. Did the install work without any errors or messages
(or is it the install itself that is failing)?
I suggest that we take this up in private e-mail as we may be getting
off-topic for the PICLIST: as you'll see in a moment, I think I have
pinned this down to a problem with my PC. For the record:
>How much memory/disk space do you have?
8MB of memory and 200Mb of free disk space.
>What kind of CPU?
TI 486DLC (equivalent to Cyrix 486).

Correct.
>Did the install work without any errors or messages

The install worked fine (no error messages).
I tried booting up with minimal AUTOEXEC.BAT and CONFIG.SYS files and
MPLAB started up fine. I assume there must be some conflict which has
not shown up with other software. I'll try replacing lines in each file
until the problem re-appears and see what conclusions I can draw.
