changing box that moves w/ the cursor

I got a script from javascript.internet.com called DHTML Tooltip Generator (at [url]http://javascript.internet.com/messages/dhtml-tooltip-generator.html)[/url]. It makes tooltips when you put your cursor over a link (like “alt=” in HTML) except it lets you write code in the tooltip. While your cursor is hovering over the link, it moves with the cursor like the alt tooltips do, the top left of the tip being at the right of the cursor. What I want to do is modify the code a bit so the tip is underneath and aligned center with the cursor, but I’m a beginner with javascript and I don’t know which part of the code instructs it to do that or how I can change it. The code goes like this (I eliminated the part at the bottom because I know it’s got nothing to do with it):

var ie = document.all ? 1 : 0
var ns = document.layers ? 1 : 0

if(ns){
doc = “document.”; sty = “”
}
if(ie){
doc = “document.all.”; sty = “.style”
}

var initialize = 0
var Ex, Ey, topColor, subColor, ContentInfo

if(ie){
Ex = “event.x”
Ey = “event.y”

topColor = “#43206d”
subColor = “#ddddee”
}

if(ns){
Ex = “e.pageX”
Ey = “e.pageY”
window.captureEvents(Event.MOUSEMOVE)
window.onmousemove=overhere

topColor = “#43206d”
subColor = “#ddddee”
}

function MoveToolTip(layerName, FromTop, FromLeft, e){

if(ie){
eval(doc + layerName + sty + “.top = ” + (eval(FromTop) + document.body.scrollTop))
}

if(ns){eval(doc + layerName + sty + “.top = ” + eval(FromTop))
}

eval(doc + layerName + sty + “.left = ” + (eval(FromLeft) + 15))

}

function ReplaceContent(layerName){

if(ie){
document.all[layerName].innerHTML = ContentInfo
}

if(ns){
with(document.layers[layerName].document)
{
open();
write(ContentInfo);
close();
}
}

}

function Activate(){
initialize=1
}

function deActivate(){
initialize=0
}

function overhere(e){

if(initialize){

MoveToolTip(“ToolTip”, Ey, Ex, e)
eval(doc + “ToolTip” + sty + “.visibility = ‘visible'”)
}

else{
MoveToolTip(“ToolTip”, 0, 0)
eval(doc + “ToolTip” + sty + “.visibility = ‘hidden'”)
}

}

Can someone help me with this? Thanks in advance.
