   [.net] transparent panels
  Hi,I've been using a tutorial which can be found here, http://www.codeproject.com/useritems/TrulyTransPanel.asp, to try and make a transparent panel. However, I've noticed that you can't "clear" out the graphics on this transparent panel, that is whatever you have drawn previously remains on the panel. The only way, it seems, to clear out what you've previously drawn is to do a  g.fillRectangle over the entire size of the panel, but once you do this the panel no longer has a transparent background. I have noticed though, that if you minimize the Form it somehow clears the graphics on the panel. I would very much appreciate any input on this matter. Also, I wish I could post my code as an attachment so that you can better understand what I'm talking about.Thanks
