A few weeks ago I suddenly began getting a horizontal scroll bar appearing when my typing reaches the right edge of the message box editor. Since I'm seeing it both at home and at work I assume this is a new "feature". I don't know about anyone else, but I find this to be a real nuisance and would prefer word wrapping. Is there a way to get back to the old message box editor where text wraps to the next line when I type to the right edge?

Thanks.
