Hi, I'm running a setup consisting of a late-2010 i7 15" MacBook Pro and a 27" Apple Cinema Display. Ever since the upgrade to Lion, I've noticed that Mission Control is incredibly slow,buggy and barely usable on the Macbook Pro after being disconnected from the Cinema Display. If I plug the Macbook Pro back in to the Cinema Display, or restart the MBP AFTER disconnection, everything works just fine. It's just as though it's trying to adapt to the smaller screen and failing terribly. Has anyone else experienced this since the move to 10.7?
