window managment bug

[Clinton Stimpson]

Does bug #6006 fall under window management?

When buttons are turned invisible, the invalidated area in the parent 
window is not repainted, so it looks like the button is still there.
Also, there's two invisible buttons that seem to repaint themselves when 
the parent window resizes, clicking on them does nothing.
Any ideas where I can go to track this down?

Thanks,
Clinton
