Fixed a bug on editor page

When testing the latest version of the project I noticed that there was a slight issue with re-sizing that caused the rightmost option panel to get pushed down and to the left when the page shrunk to a certain size.  I think this bug appeared because of a slight tweak to the editor div sizing.  Anyways, I went in and fixed it.  Tested it out on IE, Firefox and Chrome so that should no longer be an issue.
