Ok, I have a weird problem. I use 1.5.1 build 260. It seems that whenever somebody launches a game my screen goes blue with a message about a memory dump. I then need to reboot. Also, I'm getting some graphic farts during films and require an alt-tab to fix, but that's less of an issue. Any ideas? Thanks
Try different rendering configurations (Direct3D/OpenGL/Software), also turn off 3D Sound if you have it selected in preferences. See if any of this helps.
