I fixed the problem! Try to put your the sims on the windowed mode!
"The only thing you have to do is add a -w at the end of your normal shortcut.
Right-click on the game icon and select properties.
* At the very end of the Target path (after the "), put in a space then -w and click OK.
* If you want to have 2 separate icons (one for windowed mode, and one for regular), then just right-click on the game icon, select copy, then right-click again anywhere else on your desktop, select paste, and rename your shortcut and update the path accordingly. "
I catch this from yahoo!
