Using DXCore daily build 11.2.11.12102 the CR_Documentor context menu appears twice rather than the customary once.

Looking in the diagnostic log, you can see the settings getting updated twice and the context menu getting created twice.

I added a lock around the context menu add/remove mechanism but that didn't help. Looking at the log, it appears the right-click event is firing twice for every right-click. I'm not sure why that is. I'll do some more research and if I can't figure it out, I'll ask DevExpress the question.

This appears to be a problem with DXCore, not the add-in. DevExpress has reproduced the issue and is working on it.

I can keep the improvements I made with unsubscribing from events and such, but there's nothing additional I can do on the plugin side.

This issue was closed by revision r669.

Kept the event handler removal during plugin finalization as well as the additional logging added... but DXCore will need to fix the actual duplicate menu entry. http://www.devexpress.com/Support/Center/Issues/ViewIssue.aspx?issueid=B223240
