Change Content Edit box size

[dfeller]

Howdy:
This one is probably simple, I just cannot seem to find the right file to edit.
My website is 1000px wide and so the "sidebar" is 220px (Manually set) and the main "Content" column is 780px wide
But, the Content box in the admin is less than that so when I try to lay out things it does not look the same - I would like to change the width of the Content edit box in the admin section to match my real content column width. Where might I find that?
Thanks in advance

The "Content" edit box is driven by the tiny MCE module and in it's admin you will see settings for with/height...

Much thanks -
and may I say of myself - duh...
I went the hard route and tried to find a file to hard edit.
I should have known that it would be a simple setting...
Again - much thanks -
