  I just upgraded to the latest Q3 2011 bits and in trying to utilize a RadWindow I get the following error:
  
  {System.Windows.LayoutCycleException: Layout cycle detected.  Layout could not complete.
     at MS.Internal.XcpImports.MethodEx(IntPtr ptr, String name, CValue[] cvData)
     at MS.Internal.XcpImports.MethodEx(DependencyObject obj, String name)
     at System.Windows.UIElement.UpdateLayout()
     at Telerik.Windows.Controls.RadComboBox.NavigateToItem(Object item)
     at Telerik.Windows.Controls.RadComboBox.OnSelectionChanged(SelectionChangedEventArgs e)
     at Telerik.Windows.Controls.RadComboBox.SelectItemDelayedSelectionChanged(Object item)
     at Telerik.Windows.Controls.RadComboBox.NotifyComboBoxItemMouseUp(RadComboBoxItem comboBoxItem)
     at Telerik.Windows.Controls.RadComboBoxItem.OnMouseLeftButtonUp(MouseButtonEventArgs e)
     at System.Windows.Controls.Control.OnMouseLeftButtonUp(Control ctrl, EventArgs e)
     at MS.Internal.JoltHelper.FireEvent(IntPtr unmanagedObj, IntPtr unmanagedObjArgs, Int32 argsTypeIndex, Int32 actualArgsTypeIndex, String eventName)}
  
  The code to reproduce this error was taken directly from the demo site since my original version was getting the error. It is:
  

  string alertText = "The employee photo has been uploaded.";

  RadWindow.Alert(alertText, new EventHandler<WindowClosedEventArgs>(OnClosed));

   

   

  private void OnClosed(object sender, WindowClosedEventArgs e)

  {

       RadWindow.Alert(String.Format("DialogResult: {0}, PromptResult: {1}", e.DialogResult, e.PromptResult));

  }

  
  I upgraded to the Q3 bits because I was getting this error (same code) with Q2 as well.
  
  Any ideas?
