Accessible text scrolling don't work propely

[Satoshy]

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').childNodes[0],"onclick",'clickAction(0)')

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

onclickIE(document.getElementById('controls').childNodes[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').childNodes[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='normal'
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='nowrap'
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').className
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').offsetWidth
x=divW
document.getElementById('tag').style.position='relative'
document.getElementById('tag').style.left=divW+'px'
var ss=document.getElementById('tag').childNodes
for (i=0;i<ss.length;i++) {sText+=ss.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!
