Video cards, hmmm, interesting thought, it does lock occasionally to a point where only a hard reboot will do, and so far it's died twice so that I've had to boot into safe mode, and fire up explorer to download and re-install the graphics drivers. I'm running the latest set, (about 10 days was the last install) of the unified Nvidia drivers, I've got a Nvidia Riva TNT2 64 running at 1280 x 1024, in 32bit, I could go up to 1600 x 1200 and see if that changes anything I guess, failing that I'll drop back to 1024 x 768 and see if that's any better, though I'd still be interested in a Linux (or QNX, BeOS or BSD) port :)
