DnD works unreliably with the hint mask set because the one motion notify
event is usually too close to the button press event to trigger the drag. 
I've not had a problem with an event backlog even on a slow platform, but
now I'm worried.  I suppose that one could block the event on drag-begin
and unblock it on drag-end.
