while in admin panel html editor problem

In the admin panel when i want to fool with my font I cant change the size of the font because a box comes up over it =( this script is so buggy =(

You know, I actually saw this in the script the other day.  I was doing some layout work in an admin panel and noticed the code for it commented out, kinda laughed and moved on.  Now, what files was I in when I did that again?
