Having an interesting issue that I can't figure out. If you look here: http://cmw.net/conferences/radio-interactive-summit/ and hover over "marketing" in the nav bar and click on "shipping" you will end up on the shipping page. Now if you hover over "marketing" again, the menu is now off to the right (but only in Firefox). It's fine in Chrome and IE.

I cannot seem to figure out why it's only happening in Firefox.

If I remove the overflow:hidden; from the firebug editor in the code below, it works, but I can't find that CSS code anywhere. I think it's inline, but it isn't in any of the files (I did a global search).

element.style {
height: 0;
margin: 0;
overflow: hidden;
