I just got a new alienware computer that is running vista 64 bit and i installed sims 2... No problems at all, and it ran just fine... The problem was when i alt+tabbed in order to do some web browsing and went back into sims. Everything (mainly the sims) began flashing different colors and parts of the sims began to stretch (the stretching was a flashing also)... Anyone know the problem or how to fix it?
