Layout problem

Hi,

I can't get CKEditor to look the way it should, for some reason. When I put it inside my wrapper div it looks like this:

However, when I place it outside the wrapper div, it looks fine. How can the inside of the editor look like it is independant from the editor box. Changing the width only changes the outer box.

Thanks,

Jesper
