I can hear the video in the background. Did you also upgrade QuickTime when you did this? The latest version (6.1) apparently changes the way that some full-screen system calls work, and several games now just get those black screens. If that is your problem, the only fix is for the game developer to release a patch. It's apparently a simple fix (several games have been updated already), but there are probably some games out there that will never be compatible with 6.1. Nevin
