	..another one for the community.: I have some nodes on my drawing that i don't want the user to change. Normally I'd just set .locked=true, but i still need the users to be able to click them and drop items on them. I use the Diagram.GetNodeAt(position) function to retrieve the node below a drop or click, but that one doesn't work with locked objects. Is there any other way i can prevent the user from modifying a node?

	GetNodeAt(point, false, whatever) will return Locked nodes too. I hope that helps, Stoyan

	Is there any way to reach the anchorpoints on a locked object? (except programmatically)

	Do you mean you need to connect a link to the node? That won't work for locked nodes; instead of the Locked property, you might try setting EnabledHandles = None in such case. This will prevent moving or resizing the node, but allow creating links.
