I also noticed the same issues with Qt Designer and the tool pallettes, 
specifically the Object Inspector. The same issues happen there also. I 
can not use the mouse to make a selection (single or double click). Not 
sure if this is all related but might seem to be.

 Also, this is with a new Mac Pro if that matters at all.
