We appear to have found it. For some reason, a “float: left;” was resulting in the overlay of the content div over that menu div — but only in non- IE browsers.
I did try clearing cache, but had several users come back to me with the same issue, so it wasn’t a single-computer problem. A Windows one perhaps?
Mind you, the top menu is no longer seamless to the page content, but with the addition of a couple of borders, we have the look to where I’m willing to accept it. I’m inclined to believe that there may have been a float:clear that should have been added and wasn’t somewhere, but haven’t had the time to peel the entire css apart to figure out exactly what goes where as of yet. I will eventually get it to lay the way it’s supposed to, but meanwhile, we have an acceptable compromise.
