title: Silverlight 4.0: GridSplitter is splitting incorrectly
body: <p>Please help, the grid splitter in not splitting correctly to the right, the testing button content. Is there anything I've missed out in using grid splitter?</p>
  
  <pre><code>&lt;local:LayoutTemplateSelector Content="{Binding}"&gt;
