I'm not sure what happened with my company laptop still running Windows XP but it is clear that something is going wrong.
This screenshot is NOT manipulated. Actually the 'we need to close' box shows first. Then the main Live Messenger window show and I can start a conversation. As long as I don't click 'Send error report' or 'Don't Send' everything works fine. As soon as I do click any button party is over and I have to restart Messenger.
I'm also very sorry for the inconvenience....
