Open Multiple Explorers Problem?

[Thaddaeus Parker]

I created an addin for Outlook that adds a command bar and loads remote
information into memory. While I only have one Explorer open, the add-in
functions properly without errors or exceptions. Yet when I spawn a new
window for Calendar or Tasks, I start receiving exceptions and Outlook
doesn't shut down properly. I developed the add-in with C# using a COM shim
and I have each explorer that I create going into a Explorer Collection with
all the proper events.

I have noticed that when I open a new window (explorer) that everything
seems to load again from scratch and during some actions there is double
events being fired that shouldn't be especially during the send/receive
action.

I question is: How do I limit what an explorer loads if there is already a
"root" explorer open, but not activated? This is a use case that I never
expected in the beginning, but now is high on my priority list to fix.

Can someone give me some insight on what I may need to do in order for the
add-in to function properly across multiple open explorers?

Thanks,

Thaddaeus.
