Going a little OT on your post here, sorry, but there is a easy way
to do add very good cross browser compatibility if you want to.

You have NS4/IE handled, but are locking out Mozilla and Opera, which
can handle this code just fine. Adding one line will gain you a lot of
compatibility.
var ie = document.all? true : false;
var ns4 = document.layers? true : false;
var dom = document.getElementById && !document.all ? true : false;
The dom var covers any browser that supports the w3c dom, including
IE5.5+, Mozilla, and Opera 6. doc.all has advantages in IE though, so
I still use it there.

Doing it this way keeps your browser detection out of your display
logic.
function getObject(nameStr) {
if (dom) {
return document.getElementById( nameStr );
}
else if (ie) {
return document.all[nameStr];
}
else if (ns4) {
return document.layers[nameStr];
}
}
function popUp(boxName,on) {
objLayer = getObject(boxName);
if (on)
objLayer.style.visibility = "show";
else
objLayer.style.visibility = "display";
}
If you are going to lock out anyone...do it to those NS4 users ;-)
