This sounds like a bug I had when I was doing a port of the X11R4 server to
MS-DOS (for my sins, don't ask) about 4 years ago. Time has muddied the details,
and my jerk boss would insist they were proprietary anyway (he's not my boss anymore,
thank God) but I seem to remember that it had to do with the VGA board
being in 4-bit deep mode (16 colors) when the program thought it was in 8-bit
deep mode (256 colors) or maybe vice versa.
I recently had a similar occurence on a Linux laptop, where Mosaic was too
stupid to understand about Visuals other than 8-bit deep and 1-bit deep.
Shit. What a mess. I can't wait for my plan9 CDROM to arrive....

(P.S. I realize I probably haven't specifically helped Boyd, and have
whined a lot, but I hope I have pointed him at the right place to look)
