// Created a long, long time ago by Tanny O'Haley
// Update history.
// 24 Oct 2006 - Added to http://tanny.ica.com
// 14 Jul 2006 - Modified the way the iframe is added to the DOM. I no longer use 
//			innerHTML but use DOM methods.
// 15 Sep 2006 - Added a check to see if the target element onmouseout is contained
//			in the onmouseout element. If it is then I dont' remove the
//			sfhover class. I made use of the Microsoft proprietary
//			obj.contains() method.
//		 Added check to make sure that the sfhover class is not already in
//			the li element.
//
sfHover = function() {
	// Support the standard nav without a class of nav.
	var sfEls = document.getElementById("catnav2").getElementsByTagName("li");
	for (var i=0; i<sfEls.length; i++) {
		sfEls[i].onmouseover=function() {
			this.className+=" sfhover";
		}
		sfEls[i].onmouseout=function() {
			this.className=this.className.replace(new RegExp(" sfhover\\b"), "");
		}
	}
