Are you using your own custom buttons?  If so, are your buttons flickering
or is it the scrollable canvas that's flickering?

If the buttons are flickering, you might try the PlasticButton class.  I
have modified the button to work properly on Windows.  If you want a copy,
let me know.

You might also consider disabling the "live scroll" effect by not scrolling
until the MouseUp event fires.

Another solution might be to convert the canvas and its contents to a
buffered image during scrolling.
