But toplevel doesn't receive WINDOW_DEACTIVATED and WINDOW_LOST_FOCUS after disposing. This happens because we remove all events for it and its children from EventQueue due toplevel's disposing. To fix this i suggest not to remove Window-, Focus-, KeyEvents and also Sequenced- and SentEvents since they wrap some Window- and FocusEvents. For this reason i add boolean paramenter removeAllEvents to EventQueue.removeSourceEvents() (since we still need to remove all events for MenuComponents). Also i removed clearStaticWindowRefs() method from KeyboardFocusManager (this method was introduced by Brent for quick fix of this problem in Merlin). ###@###.### ======================================================================
