Shoutbox

I've had this 3 or 4 times but could not reproduce it.  It all fixes up if you close the chat you just opened and re-open it.  Also I found it was only when you clicked on the new chat tab, but if you click to an old one it looks as though it is fixed.  I never had it show multiple chats, though I think you are running Vista where I'm running XP which may be the reason for that
