Hello all- I have the MBP in my signature, with OS X totally up to date at 10.7.2. Whenever I want to reveal all windows with the F3 key shortcut, there is a terribly jerky and sometimes slow transition to showing all of them, in which the background and application windows change size to be revealed slightly after one another. I ran a permissions repair and checked software update for any possible missing fixes- neither produced a change. What do you all recommend? Thank you.
