Cheers Creamhackered who let me know that Microsoft have put out build 0077 of Messenger (now at 4.6) No word on changes and I don't see any immediate changes in the program. Updates are good tho.
Send instant messages with cool, new emoticons, call anywhere in the world from your computer, see when someone's typing, page a contact's mobile phone, send pictures and music to your friends, and much more.
