EVT_ENTER/LEAVE_WINDOW: Perhaps one approach to reliable implementation of
EVT_LEAVE_WINDOW is to set a flag when the mouse pointer is in a window,
then in idle time, check this window.
If the flag is set but the mouse pointer is outside the window, then
it's time to generate an EVT_LEAVE_WINDOW. This would be necessary at
least for the case when the mouse cursor goes off the application windows,
and no motion event was generated (i.e. you moved the mouse quickly!).
If it goes from one app window to another, you could generate the event sooner.
