Riddle me this, Xperts --- R3 server bug or pilot error? This is a case of not
getting the expected events during an active button grab. But why?

The scenario: user presses on button window B to pop up menu window M.  The
pointer is now grabbed by B with owner-events False.  The event masks of both B
and M have previously been set to select for EnterWindow.  Therefore, when the
user moves the pointer (with the pointer button still pressed) off B and onto M,
an EnterWindow event should be reported to B, i.e.  as a result of entering M.
But it isn't.  Why?
