	I'm not sure if this is causing your problem, but the &quot; and
using the actuall numerical index value, may be causeing at leat some
problems. Also IE 3.0 does not do a very good job with javascript and has
peoblems witht the rollovers anyway. Try using this code instead:


<!-- hide script

//image preload
        mainu = new Image();
        mainu.src = "images/main.gif";
        mainh = new Image();
        mainh.src = "images/main-h.jpg";
        broadcasth = new Image();
        broadcasth.src = "images/broadcast-h.jpg";
        coolh = new Image();
        coolh.src = "images/cool-h.jpg";
        coolc = new Image();
        friendsh = new Image();
        friendsh.src = "images/friends-h.jpg";
        searchh = new Image();
        searchh.src = "images/search-h.jpg";
        mailh = new Image();
        mailh.src = "images/mail-h.jpg";

//MouseOver Function
function LightUp(ImageX,Text) {
   document[ImageX].src = "images/" + ImageX + "-h.jpg";
        window.status = Text
//MouseOut Function
function DimDown(ImageX) {
   document[ImageX].src = "images/" + ImageX + ".gif";
//End JS Script hide-->


if you wish to see this code in action go to:
