title: Delphi buttons show white border on Aero glass
body: <p>I have been trying to find a good-looking design using Aero in Delphi 2010. One of the obvious uses one sees, is where the glass frame is extended to include the OK/Cancel buttons at the bottom of the screen. I notice though that this doesn't look quite right in Delphi 2010 - there is a white border all around each button.</p>
  
  <p>This image shows the problem: the top 3 buttons are from my app, the bottom two were taken from Paint.NET's Layer Properties dialog.</p>

  </p>
  
  <p>I tried various combinations of DoubleBuffered and a few combinations of placing the controls on other controls first, but the problem remains. Any ideas?</p>
