Duplicate Mail Viewer Window appearing without apparent reason

Question

This isn't a leopard Mail problem per se. It was exactly the same in Tiger and stayed this
way after an archive and install (preserve settings).
I connect via imap to a server (Novell groupwise)
If I click and hold on the Junk folder icon and do Delete Junk Mail
This works, but automatically also opens up a new Mail window with all the folders to the left
etc as if I asked it to open a New Viewer Window.
It also happens some other times but I can't recall the conditions.
Yes, I have tried moving the preference file out to the desktop
and no, there is nothing special in any rules. I just have the Junk rule
and stop rule, stock standard.

Hi Peter,
Since it is a different provider, I guess we can't just blame the provider.
The only thing that seems to work with the iPad is to tell the unit to delete the email account information and then reenter the information manually. Doing that every few days is getting frustrating for the users over on the other forum.
That may be the only solution for your case, delete the account information and reenter all of it. If you go that route, I would say get rid of all of it, not just the password item. Something strange is going on here with OS's resetting information unilateraly.
