I have a Mdi window with FormBorderStyle.none. I have one user
control (holding a few normal controls) that is set to docking fill in
the Mdi. I use the mouse down, move, and up events on my control to
resize the Mdi. It works. However, as I resize the form the painting
is very choppy, showing the inner controls drawn at different sizes
until I stop resizing. If I turn the FormBorderStyle back on and use
the forms borders to resize I do not see this choppy drawing effect
and it looks great. What am I doing wrong?

Thanks
Bob
