Random NotSupportedException on showing ContextMenu

[Marcin]

Hi,

users reports, that 'sometimes', when they do a few right mouse button clicks on elements with ContextMenu binded, they get an exception with the following xaml:
---------------------------

---------------------------
Unhandled exception: System.NotSupportedException: Specified method is not supported.

   w System.Windows.Controls.Primitives.Popup.SetWindow(Window associatedWindow)

   w Telerik.Windows.Controls.RadContextMenu.OpenPopup()

   w Telerik.Windows.Controls.RadContextMenu.OpenContextMenu(Object sender, EventArgs e)

   w Telerik.Windows.Controls.RadContextMenu.OnElementWithContextMenuMouseClick(Object sender, MouseButtonEventArgs e)

   w MS.Internal.CoreInvokeHandler.InvokeEventHandler(UInt32 typeIndex, Delegate handlerDelegate, Object sender, Object args)

   w MS.Internal.JoltHelper.FireEvent(IntPtr unmanagedObj, IntPtr unmanagedObjArgs, Int32 argsTypeIndex, Int32 actualArgsTypeIndex, String eventName, UInt32 flags)
---------------------------
OK   
---------------------------

It seems not to occur while doing this clicks slower, but in some situation its a bit annoying.

Thanks for You help in advance,
Best regards
