My add-in is causing a minor problem with large files in Inbox.

I have Download Only Headers For Items Larger Than set to 10k. Any larger emails will display only their headers until I Mark To Download and Process All Marked Headers. This should cause the entire body to display, but with the add-in enabled they will not. I have to click onto another email then back, sometimes repeatedly.

The code that causes the problem is the same as in my previous Post

Add-in problem: First email in outbox gets stuck


It's where we are trying to add items to the context menu if the user has right clicked on an email.

if (_explorer.Selection[1] is Outlook.MailItem)

Touching the email seems to cause this problem, but I can't think of how to avoid this since these are the emails we want to change the menu for.

Is there no way to reset the Selection to its previous state?.
