title: Resizing the form issue
body: <p>I'm getting problems when trying to set the location of a couple of groupboxes...</p>
  
  <p>This is a picture of the application in default size,</p>
  
  <p>the groupboxes are in the middle of the form, and that's what I want.

  <p>This is another picture, when the application is resized,</p>
  
  <p>the groupboxes are moved to the left side, they are not still in the middle</p>
  
  <p>The anchor property of the groupboxes are "Right" (I've tried all combinations)

  <p>And this is a picture of the application when is full maximized,</p>
  
  <p>the groupboxes are mover to the right side.

  <p>I want to preserve the groupboxes in the middle of the tabpage when resizing.</p>
