Might be easiest to take a look at the problem first, link here.
In Firefox, when you hover over the first menu item (Shop All Departments) you're not able to click on it, which is necessary to get to the website's store. Actually, any menu item that has a child isn't clickable. Weird thing is that it works in IE. I haven't checked it in other browsers yet, and the site is still under construction.
Another thing we noticed is that in IE7, the menu doesn't float correctly. I know this is most likely a CSS issue, but just thought I'd throw it out there in case anybody knows how to fix that. As long as I've been making WP sites, I'm still so confused on how to fix things for IE. I wish it would just die.
Ok, sorry about the rant and I appreciate any help :)
