that's a problem.
my guess, it might be a video card problem. I ran into something like that when trying to play I-war. it was a pain in the ass, but I managed to find a forum about it. I was directed to a program that lets you play games that only ran on the old Voodoo video cards. i had to tweak it a couple of times, but now it works (ya!).
does anyone know what video card GF was intended to be used with?
