Hi, I am writing an add-in which listens out for a user clicking on specific components within an assembly to mate them together. I'd like the user to be able to clear their selection by clicking somewhere in the graphics area. The selection is cleared by SolidWorks automatically when the user clicks on the graphics area, however there are some values stored in memory by my application which need to be cleared also.

Is there a way I can listen for this sort of event so that I can clear the values?
