example program to illustrate bug

Description of Problem:
Using Windows Forms under linux, when you click the mouse you get the following
sequence of events:

MouseMove
MouseDown
MouseMove
MouseMove
MouseUp
MouseMove

Doing the same thing in Windows under Microsoft .net gives you:

MouseMove
MouseDown
MouseUp

The MouseMove events in between MouseDown and MouseUp when the mouse has not
actually moved may cause unintended consequences for an application developer,
although this is easily worked around by checking the MouseEventArgs.Location
to see if the mouse has actually moved (although this property requires the
net 2.0 libraries).  I'm attaching an example program to illustrate the
problem.  I have not tested this in Windows with Mono.
