I recently upgraded the video card in my G4 tower to an ATI 8500. Now I've lost the ability to play several older games. Specifically I now get a black screen instead of the game screen. I can hear the video in the background. So I know the game hasn't locked up. I remember reading that it was caused by the black background being drawn in front of the game instead of behind. I know that this was a fairly common problem and there was a simple cure but I've forgotten what it was and where I read about it. (CRS) Does anybody have any info on the cure?
