  I seem to be frequently getting the exception below when I open a RibbonForm, not every time but enough to be REALLY anoying.

  Exception: Object reference not set to an instance of an object.
  
  Stack:
  
  at C1.Win.C1Ribbon.C1RibbonForm.OnActivated(EventArgs e)
  
  at System.Windows.Forms.Form.set_Active(Boolean value)
  
  at System.Windows.Forms.MdiClient.WndProc(Message& m)
  
  at System.Windows.Forms.NativeWindow.Callback(IntPtr hWnd, Int32 msg, IntPtr wparam, IntPtr lparam)

  Any help would be greatly appreciated.
