Accessible text scrolling don't work propely

Hi all,
i've implemented this text scroller from websemantics.co.uk (thanks to
Mike Foskett) but there are some problems with long's text.

There's an example here http://www.morrisonspub.it/new/scroller/

As you can see the text showed is not complete.. :(

How i can solve this problems?

This is the js code:

// Accessible Scroller by Mike Foskett
(http://www.websemantics.co.uk/). Retain this message and you may use
the code freely.

var speed=10 // speed of scroller
var step=3 // smoothness of movement
var top="#top" // name of anchor used as page top when clicking
start / stop / show
var Start= "Start" // Text for start link
var Stop = "Stop" // Text for stop link
var Show = "Show" // Text for show link

var x, scroll, divW, sText=""

function onclickIE(idAttr,handler,call){
if ((document.all)&&(document.getElementById)){idAttr[handler]=new
Function(call)}
}

function addLink(id,call,txt){
var e=document.createElement('A')
e.setAttribute('href',top)
e.setAttribute('onclick',call)
var linktext=document.createTextNode(txt)
e.appendChild(linktext)
document.getElementById(id).appendChild(e)
}

function addControls(){
addLink('controls','clickAction(0)',Stop)

onclickIE(document.getElementById('controls').chil dNodes[0],"onclick",'clickAction(0)')

document.getElementById('controls').appendChild(do cument.createTextNode('
| '))
addLink('controls','clickAction(2)',Show)

onclickIE(document.getElementById('controls').chil dNodes[2],"onclick",'clickAction(2)')
}

function stopScroller(){clearTimeout(scroll)}

function setAction(node,callvalue,txt){
var c=document.getElementById('controls')

c.childNodes[node].setAttribute('onclick','clickAction('+callvalue+' )')

onclickIE(document.getElementById('controls').chil dNodes[node],"onclick",'clickAction('+callvalue+')')
c.childNodes[node].firstChild.nodeValue=txt
}

function clickAction(no){
switch(no) {
case 0:
stopScroller()
setAction(0,1,Start)
setAction(2,2,Show)
break
case 1:
startScroller()
setAction(0,0,Stop)
setAction(2,2,Show)
break
case 2:
stopScroller()
setAction(0,1,Start)
setAction(2,3,Start)
x=0
document.getElementById('tag').style.whiteSpace='n ormal'
document.getElementById('tag').style.left='0px'
break
case 3:
startScroller()
setAction(0,0,Stop)
setAction(2,2,Show)
x=divW
document.getElementById('tag').style.left=x+'px'
}
}

function startScroller(){
document.getElementById('tag').style.whiteSpace='n owrap'
var p=document.createElement('P')
p.id='testP'
p.style.fontSize='25%' //fix for mozilla. multiply by 4 before using
x-=step
if (document.getElementById('tag').className)
p.className=document.getElementById('tag').classNa me
p.appendChild(document.createTextNode(sText))
document.body.appendChild(p)
pw=p.offsetWidth
document.body.removeChild(p)
if (x<(pw*4)*-1){x=divW}
document.getElementById('tag').style.left=x+'px'
scroll=setTimeout('startScroller()',speed)
}

function initScroller(){
if (document.getElementById && document.createElement &&
document.body.appendChild) {
addControls()
document.getElementById('controls').style.display= 'block'
divW=document.getElementById('scroller').offsetWid th
x=divW
document.getElementById('tag').style.position='rel ative'
document.getElementById('tag').style.left=divW+'px '
var ss=document.getElementById('tag').childNodes
for (i=0;i<ss.length;i++) {sText+=ss[i].nodeValue+" "}
scroll=setTimeout('startScroller()',speed)
}
}

function addLoadEvent(func) {
if (!document.getElementById | !document.getElementsByTagName) return
var oldonload = window.onload
if (typeof window.onload != 'function') {
window.onload = func;
} else {
window.onload = function() {
oldonload()
func()
}
}
}

addLoadEvent(initScroller)


Thx a lot!
