I have a customer who has the annoying message of Messenger being signed in on two computers/locations, but it happens differently than what you'll usually see. She uses MSN Explorer and signs in as usual, and that signs in the Windows LIve Messenger just like you'd expect. Nothing further happens until she clicks on the e-mail button to go to her MSN/Hotmail box. THAT is when it complains that Messenger is signed on in two locations, sometimes right when you go to the box, sometimes it waits until you're doing something with a message.
I've done the normal stuff to try to get it to stop. I took the advice the Microsoft gives to have Messenger not sign in automatically and it didn't help. I also took Windows Messenger out of the Windows Components, and I also ran the removal script that dougknox.com provides. Nothing has gotten it to stop yelling, except, of course, avoiding checking e-mail. Any ideas?
