I just bought a new computer and now I can't get Quake or GLQuake to run.
Both give me the following error : The first DOS window will load up a
second window (with the rocky background texture) but only for a split
second.  Almost immediately, that 2nd window disappears, leaving me with the
first and nothing else (the one that calls qlaunch with the -mpath
extension).  Nothing is on my windows toolbar, and nothing is on my
desktop - except for this useless 1st window.

(Typically, the first window would open up the 2nd, which would open up the
3rd in full screen size where the game is played.  That's when it worked.)

My configuration is :

- BX motherboard
- Matrox Millennium G200 video card
- Diamond Monster II (12 megs)
- Soundblaster Live! sound card
- 256 megs of RAM
- P2/400mhz CPU

Can anyone tell me why I can't run Quake with this setup?  I have the latest
SBLive drivers (released 3 days ago) because someone told me he had problems
with his using Quake 2.

Note: I tried running it in DOS mode (without the Windows shortcut) and it
does the same thing : hangs at the qlaunch/mpath command line).  And the
exact same files (copy/pasted) work fine at the office.

If this is a common problem, could someone send me the fix or instructions
on how to rectify it?

Thanks a million,
