	When dragging one endpoint of an arrow instance, my ValidateAnchorPoint handler is called, but args.Arrow seems to always be null. Is there something I'm not setting up properly? Thanks, -lipp

	You can ignore the event when args.Arrow is null. The control raises that event once for each anchor point in a node without specifying an arrow, in order to determine whether the node accepts any arrows at all. After that the event is raised again for the arrow that the user draws at that time. Stoyan

	Ahh...thank you. As a related point, the documentation for AttachConfirmArgs doesn't mention the "Node" field. What is that for? Thanks again, -lipp

	Node is the same node as either Origin or Destination, depending on which end of the arrow is being moved. Stoyan
