I was back to the drawing board trying to implement the following
routine (which I've posted in about in the past):

When I select a new email in the explorer:
* Check to see if the last one was flagged. If not, Archive it.

I need to handle the case where I delete an email and therefore
trigger the SelectionChange event.

When I delete an email, by the time I get to the SelectionChange
routine, the email looks to have already been deleted (same for manual
moves).

I hope that explains what I'm trying to do.
