We have an application that does not run properly under open
windows with "Click select: (click a mouse button in a window to
give it the focus) enabled.  When we traced the events it is
getting, it seems that when the left or middle mouse buttons are
pressed over a window that currently has the input focus, the
application in the window gets the sequence of events:

LeaveNotify (leaving the window)
ButtonPress (indicating the button)
EnterNotify (entering the window)

When the button is released, a simple button release event is
generated.

The trouble is the application is confused by getting the button
press when it thinks the mouse is not in the window.  The Leave and
Enter events in this sequence do not make sense to me.  Are they a
bug or a feature?  If they are a feature, could someone explain
why they are sent when the mouse never leaves the window in
question?
