hi, I have a shared computer at the office with XP professional.. I have loaded MSN messenger but my address is in the pop up menu and it loggs in without the need for a password...
I have been all through the MSN options with no joy... I think it is an XP setting that is doing this... how can I stop it?

Thanx ..mark
