I will repeat my request from your last NSTrackingArea query:
I'm not certain of the answer to this question, but what does your
-updateTrackingAreas look like? If you follow Apple's erroneous example
and recreate your tracking are every time this method is called, you
*will* drop -mouseExited: events on the floor. A correct override of
-updateTrackingAreas only creates and installs the tracking area if it
has not already been created and installed.
