Wait... so you mean the white "box" that you type messages in when doing a post like this one?
Where there are these above the box:
:wink:

:shifty: :timbits: :cobra: :spidey:
Because, that's normal if it scrolls UP while you're making a bigger post... just a quick reply, nothing should go wrong.
THIS LINE HERE, is where things start to scroll up by one line.
Now another line.
And so on.
The message block this board format uses is pre-defined and regardless how much bigger I made it, it would still move if you typed more content than the space would provide.
It's a part of the board.
If you guys are talking about something completely different, then you need to describe it better.
