So up until yesterday, Hotmail/Outlook had a handy little up/down arrow in the header bar (it WAS right next to the X for closing a message) that allowed you to advance to the next message without going back to the Inbox first or deleting the message (I have my options set to advance to the next message if I delete).
Imagine my surprise when I checked my email today and those little arrows are gone!!!! Only the "close message" X remains. This is so useless and frankly DUMB. I shouldn't have to keep going back to my inbox if I want to hang onto a message, AND THEN manually click the next message. What a pain. The arrows seems to be disappearing and reappearing at random from the header bar.
