EVENT.DEACTIVATE doesn't work with safari in mac, is there any possible way to do this. (MouseEvent.MOUSE_LEAVE is not the same as detect when user lost the focus of the window) so I ran out of alternatives.

              Listen to the blur event via JavaScript and dispatch it to your SWF via ExternalInterface.
