I know we're all mad about applications popping up and stealing focus but what about when they don't?
If you go to Expose Mission Control view and click on a window, it's moved to the top and gains focus. Makes sense
If you go to Mission Control view, put the cursor over a window, then close the view, the window is moved to the top but it doesn't gain focus. Whoever decided this thinks they are very clever but it results in me entering text into the wrong window many times a day
