Resize of editor window

Hey,

In FCKEditor there was a neat solution to resizing the editor window using js. Someone has oultined it here:

http://cksource.com/forums/viewtopic.php?f=5&t=4837&p=32257&hilit=_Frame+frame+height#p32257

It was easy to get the iframe and adjust it's height i.e.

frame = document.getElementByID( instance_name+"___Frame");

However, this doesn't work in CKEditor 3 - any ideas how to achieve the same thing - i.e. get the frame/div etc the editor is in so that the height and width can be manipulated?

Cheers
