I have a Windows XP system that, until today, ran Fitzquake 0.80 just 
fine. Today ...

"Couldn't set fullscreen DIB mode" and it exits, without an opportunity 
to change to windowed, and without an explanation.

I haven't made any changes to the system since the last time it was 
working (which was yesterday). In particular, I haven't changed the 
video drivers or messed with the video settings. In case it matters it's 
an nVidia GeForce2 card (an older card, but fine for classic Quaking).

Task manager shows a "commit charge" of 571M; the machine has 1GB 
physical ram and about half again that available including swap. So it's 
not an out of memory problem.

Does anyone have a clue what would cause it to stop working like this? 
Keeping in mind that I haven't changed anything, either with Fitzquake, 
or quake in general, or the video settings, or the system in general, 
since yesterday when it functioned normally.

I can only guess it may have hosed itself on exit last time it was run, 
in which case I need to know what config file to tweak or replace with 
default. Keeping in mind I can't get into the app to change things via 
the options screens. :P
