I was able to resolve me issue with HMenus showing up in FireFox, it had to do with a conflict with the Flash. I was able to get it fixed, however, I am still not seeing the menus display on mouse-over.

Again, if anyone has the time to take a look at http://www.tradeexpressions.com from both IE and FireFox and let me know if you have any ideas, I would really appreciate a 2nd set of eyes, as the <ul><li> nesting for the navigation appears all in order to me.

Thanks much,
Ian
