Prior to Snow Leopard, you could use swipe up to see the desktop and then swipe down to come back to your previous window. Now you must swipe up again to go back to your original window. The up/down movement is ruined in Snow Leopard... Thanks
I have had some issues with swiping as well as the dedicated key for Expose. Sometimes, depending on what I have open, I will swipe or use the F3 key for Expose and then the windows will quickly move and come back, but if I use the active screen corner feature Expose works just fine every time. Strange??
