Source editor appears short

Hi all,

I'm just getting into CKEditor 4. I'm trying to set up the editor full screen.

Using a absolutely positioned DIV, I can set CKEditor to to replace a conaining textarea 100% in the options no problem.

Howver, when using the source editor the source code text box only drops two lines. I've switched to using the popup source editor instead which works around the problem, but just wondered why the source doesn't fill 100% height while the wysiwyg editor works fine.

Thanks.
