The enclosed app behaves correctly in XP/2003 but misbehaves in Vista.

I have included a minimal app that demonstrates the problem. It has a textbox within a groupbox on a form that has a Paint override.

As you hover your cursor over the textbox you will see the text within it vanish.

This problem still occurs on RC1. I've included another sample applet.

The problem appears to be with the vertical scroll bars in the text box. If those scroll bars are removed from the box's default properties, then the prolem does not occur.
