I'm having problems with icons showing up on a Firefox window that is opened using thickbox. If I open the frame by itself, the icons show up fine, but if I open the window using thickbox, the icons don't show up. I get lots of warnings in the Firefox error console, all apparently related to editor_gecko.css. It works fine in Chrome - the problem is apparently only in Firefox.
