title: Overlapping Panels in C#
body: <p>I am using the GUI forms builder in c#. I have a TransparencyKey set, and the backGround color of the whole form is set to that Transparency key so the background of the form seems invisible. I also have a login panel that appears at first and after the user logs in it disappears and the other panels become visible. This all works except when I attempt to overlap any of the panels. Send to back or bring to front make no difference. If even one of the panels overlap a little both of those overlapping panels disappear? What could be wrong? </p>
  
  <p>Cheers
