What does "the transparency is the other application" mean?

Hi Javier,

I didn't quite get the problem. Can you elaborate on it, pls?

I think I know what it is refering to: when you open a new application and
you move it in front of the form and then away, in the place where the
background image is displayed you see a "remainder" of the other form's
appearance. That is probably because what is under the transparent image
doesn't get repainted. You probalby need to override the Invalidate method
and everytime the form is invalidated you must repaint the background too...
