From what I can see it only happens in IE9 and only when the compatibility mode is on. I asked one of my friends to take a look and it works fine on his PC in IE9, so it looks like it may be isolated to certain OSs too.

I have been looking at CSS and from what I can see everything is kosher. I appreciate any feedback you may have!
