I am working with Mindfussion.diagramming diagram. I can draw an node on diagram. when i trying to draw node with using mouse left button and immediately click right button from mouse it opens context menu and raises an exception as

{System.NullReferenceException: Object reference not set to an instance of an object.
   at MindFusion.Diagramming.Silverlight.InteractionState.Start()
   at MindFusion.Diagramming.Silverlight.BehaviorBase.OnMouseMove(MouseEventArgs e)
   at MindFusion.Diagramming.Silverlight.Diagram.x2c5d1da1234c3a6a(Object xe0292b9ed559da7d, MouseEventArgs xfbf34718e704c6bc)
   at MS.Internal.CoreInvokeHandler.InvokeEventHandler(UInt32 typeIndex, Delegate handlerDelegate, Object sender, Object args)
   at MS.Internal.JoltHelper.FireEvent(IntPtr unmanagedObj, IntPtr unmanagedObjArgs, Int32 argsTypeIndex, Int32 actualArgsTypeIndex, String eventName, UInt32 flags)}

I cann't  understand what's the problem. Please help me.

Call diagram.CancelDrag() before showing the context menu.

I hope that helps,
Stoyan
