I created an application where the user is able to select a sertain shape and then create it by clicking on the flowchart. However, one of this shapes is a mouse cursor indicating a "no shape selected" state. Allthough I can avoid a box being created with a click on the flowchart, users are still able to create a box by dragging the cursor.

This behaviour is similar to many dev IDEs (ie Delphi, and probably VS2005(?))

Is it possible to somehow prohibit the user to create the new box by dragging the mouse, while still being able to edit (move, select etc) other objects that already exist?

I have seen the StaticMode property, but this makes the entire flowchart read-only.
