After upgrading to Snow Leopard, I am experiencing something rather very strange. I have a late 2008 MBP, which has the four finger swipe up/down(to show desktop) built into its touchpad. Now, when I swipe up, the app windows hide and it shows the desktop, and then when I immediately swipe down(without releasing my hand), the Windows come back. No problem till now, but the trouble arises once I release my hand after the swipe down motion, and the windows go back to hiding(and remains stuck there), until I have to do the swipe up motion again to bring the windows back on the desktop! Been used to the Leopard interface for so long, I guess its a habit for me to swipe up, and immediately swipe down and it automatically quits the show desktop mode. Now, I have to swipe up, release my fingers and then do a swipe down for this to work. TBH, its kind of frustrating. Is this a feature I just have to deal with it or a bug?
