I have tried all of the Window key combinations I could find on the net to see the Flip 3D application switching but nothing seems to work. Win-Space, Win-Alt, Win-Tab are what I have tried. Does it work for anyone else? If so, is there somewhere that it needs to be enabled or am I using the wrong key combination? I have even tried switching to a copatible video card (Radeon 7550) since my other just came up as VGA compatible.
