I believe this problem lies in the new layout only, I've never had it before. maybe a messed up code or something.
when I type in the message area to post a topic and I have a lenghty enough post for the scrollbar to kick in, it bounces it back up to the top. this is REALLY getting on my nerves as I can't see what I'm typing as I type it, only if I stop and scroll back down. it also makes it impossible to select a small snippet at the bottom because it bounces it back up again.
