Every time I open My computer I get the 8 of the following messages:

"To use sharing folder, you need to sign in to Windows Live Messenger"

I don't use Windows Live Messenger (though my children do use MSN and rather annoyingly I get MSN popping up with messages in my account, so I know it is there). All shared directories are shared correctly.

I have just changed from a Netgear router to a BTHomehub and have changed settings, so this may have something to do with it.

I am running XP SP3 and using a wireless network.

Any ideas about this?
