Periodically, after my mid 2011 27" iMac has been asleep for a time, Misson Control will not work. I usually use a Magic Trackpad and three-fingered swipe upward to get to Mission Control. After a long sleep, this will not work, but other swipes will. My F3 key (Mission Control) is dead and the app icon in LaunchPad won't work. I have to restart the computer to get Mission Control back. Does anybody have a fix?
