Hello Lavin,
This feature is part of the Aero feature in Vista. It will need to be enabled before the Flip-3D (Switch Between Windows) will work. Double check to make sure that you have the latest graphic drivers installed, you have updated your WEI score, and that you have a Windows Aero color scheme selected in Advanced Appearances (Personalize).
Hope this helps,
Shawn
