Nav/Log in bar too bid in IE

How do I change the size of the nav bar? It looks fine in mozilla, but in IE it's a little longer than the rest of the site and looks funny. You can see it here:

As you are using the "classic" template and stylesheet.css I was surprised to see this entry - and the cause of your issue:
Find this:

#navMainWrapper, #navSuppWrapper, #navCatTabsWrapper {
	margin: 0em;
	background-color: #abbbd3;
	background-image: url('../images/tile_back.gif');
	font-weight: bold;
	color: #ffffff;
	height: 1%; padding-left:0.2em; padding-right:0.2em; padding-top:0.5em; padding-bottom:0.5em
	}

change to this:

#navMainWrapper, #navSuppWrapper, #navCatTabsWrapper {
	margin: 0em;
	background-color: #abbbd3;
	background-image: url('../images/tile_back.gif');
	font-weight: bold;
	color: #ffffff;
	height: 1%;
	}

you do not want to pad the Wrapper!
