Adjust editor height to content

Hey,

I'm using FCK Editor 2.6 BETA for my blog system and now i wonder if i can let the editor height adjust to the content inside of it.

I hope i am clear and someone has the solution...

I did find the solution, but it's still doesn't work well in Firefox!
I've readed this:

and

But it still flickers...

Greetz,
Marc
