This fix seems to make it behave a lot better!

I think I can still trigger this issue though, by opening Outlook 2003
(sorry :X), and holding down F9 for a bit (send/receive shortcut). When
the send/receive query contains about 5+ actions, outlook stops
responding.

But still a LOT better then before. At least when the problem occurs,
other users can still login, which wasn't the case before.

Cheers,
