I have been struggling with getting two types of addins to work together for some time now. I have created an editor extension addin and have been able to listen to events on start editing with success. I also have created a regular (desktop) extension and can check it on and off with success. What I am having trouble with is that I would like the editor event listener to only work when the extension in ArcMap is enabled (checked). I am working with the desktop extension addin now but whenever I add the event handlers to start listening when the extension is enabled it causes ArcMap to crash. Any ideas or sample code would be greatly appreciated! The handlers are commented out since that is what is causing ArcMap to crash.
