This happens only on my new MacBook Air 11" and only since I upgraded to Mountain Lion.

 

Whenever my mouse pointer is over a Numbers document (not the window title, but the actual document), CPU usage by Numbers.app goes to 70% and stays there until I move my mouse somewhere else.

 

Did anyone else experience this?
