anyone have any pointers on why the nav bar isn't 100% of the window width in FF but it is in IE7 ? http://www.intranetintelligence.com/ I've sorted out that it's the body background-color showing through (I temporarily set it to grey to make it more visible) but can't sort out why the nav isn't expanding to full width in FF. essentially the same code is working as I expect on this site http://bluemoonoasis.com/ so I'm lost. thanks joel
