I have a Sapphire ATI Radeon 9600XT 256MB DDR AGP 8X and it works great with everything except when I try to play Warcraft 3: Frozen Throne. It will lock up everything after about 10 minutes into play and I will have to restart the PC. I have the latest updates from ATI's website and the other graphics cards I have tried have worked fine w/ the game in the past. Am I missing something, is this a common or known problem? Any help would be appreciated.
