Community,

Is there a reason that the MouseUp event for a windows form TreeView control
fires when the mouse is moved while the left mouse button is held down?
I think you'll find this one repeatable. Make a scratch windows form
project. Place a TreeView control on the form. Add some nodes to the
control. Add an event handler for its MouseUp event. Set a breakpoint in
that event handler. Watch what happens. I'm using VS.NET 1.0.
If you have an empty TreeView control, the MouseUp event fires when the left
mouse button is pressed, even before the mouse is moved. Huh.

Thanks,

I am able to repro the behavior you describe on a .NET 1.0 machine. I
would consider that to be a bug.
 
Where do we go from here?

Exactly how do you define "seems to work fine"... as in, A) it correctly
does NOT fire MouseUp or B) MouseUp is still firing but you feel that its
the intended behavior?

The MouseUp event IS firing at the appropriate time in 1.1 - when the mouse
button is released and not when the mouse is moved.
