I tried using Google to find a solution but I couldn't find one. When I start Halo and the menu loads, the game appears to minimize itself but I can still hear the main menu music and sound effects when I move my mouse around. The only way I can exit the game is if I use alt + F4 which closes it, causing a gathering exception data dialogue box to appear. I haven't played this game in a while though, probably not since last summer so I'm thinking it might be a driver issue. I have a genuine copy of Halo CE, a GTX 460 video card with 290.53 drivers and my current OS is Windows 7. Any help would be much appreciated. In the mean time I'll probably try re-installing Halo... again. [Edited on 02.13.2012 11:43 AM PST]
