WYSIWYG and IE Width problem

[Greg]

If I activate one of the WYSIWYG editors and try to edit a page in IE the width of the WYSIWYG textarea is wider than the screen and I am unable to scroll the page to edit it. The WYSIWYG menu bar actually extends past the right side of the screen as well. The CSS is using overflow: hidden; so I don't see a vertical scrollbar either.

To correct this I put width: 100% in the div.pageoverflow selector of the admin\themes\default\css\style.css and I can now edit my entire page using the WYSIWYG.
Works in IE and Firefox.
