title: .NET PowerPacks RectangleShape flickers on form resize
body: <p>I can do something as simple as: </p>
  
  <ol>
  <li>Create a new .NET form application</li>
  <li>Put a single RectangleShape onto the form</li>
  <li><p>add the following into the InitializeComponent method in the designer code</p>
  
  <pre><code>Me.SetStyle(ControlStyles.AllPaintingInWmPaint Or _
      ControlStyles.UserPaint Or _
      ControlStyles.DoubleBuffer, True)
  Me.UpdateStyles()
  </code></pre></li>
  <li>Run the program</li>
  <li>Resize the form</li>
  <li>Watch angrily as the rectangle flickers</li>
  </ol>
  
  <p>Is it possible to get rid of this? Or is the ShapeContainer internally flawed and I need to find a different solution?</p>
