function navGo(navRoot)

	if (navRoot && navRoot.childNodes)

			var node=navRoot.childNodes[i];

			if (node.nodeName=="LI")
			{
	//			alert("node #"+i+" name="+node.nodeName+" id="+node.id);

				node.onmouseover=function()
				{
					this.className+=" over";
				}

				node.onmouseout=function()
				{
					this.className=this.className.replace(" over", "");
				}
			}

			navGo(node);
