Before Bob changed it, if you had 50 unread messages and you read one of them and had to leave, it would not show that you had 49 still unread. If you click on that button, you can read one and then go back to the other 49 later. I love that button! <img src=http://www.feebleminds-gifs.com/tweety.gif> <embed src='http://' autostart=true height=0 width=0>
