  Is it possible you are changing the event mask? In particular, if you are
disabling the mouse-up events, later programs will not be able to get the last
time the mouse button comes up, which is a common means of getting the start
time for timing double clicks. If you disable events in the event mask, you
should make sure to restore them before you exit.
