Yahoo Messenger glitch.

When typing in an IM in Yahoo Messenger, the scroll bar on the right normally keeps what you are seeing and adding to in sight. That is to say, it automatically scrolls down with you. You can scroll up to review.

MY Yahoo Messenger does not do this and it’s maddening. Now, every time a new bit of text is entered by either party, the scroll bar AND text jumps up to the first lines at the start of the conversation. So every single text entry by either party requires me to grab and scroll back DOWN to the bottom to see what was just entered.

Any idea if this is some bizarre preference I can fix, or is my Yahoo corrupt?
