scroller speeding up on refresh

[1DMF]

hi,

I have a simple marquee effect, I use AJAX to update the DIV (ie. scroller content), only doing this stops the content scrolling, so I added a call to initalizemarquee(); when the AJAX return, only the scroller speeds up, and each time the div is refreshed the scroller gets faster and faster. why is this and how to I update the div and kick of the scroller without it getting fater each time..here is the JS

var delayb4scroll=500 //Specify initial delay before marquee starts to scroll on page (2000=2 seconds)
var marqueespeed=1 //Specify marquee scroll speed (larger is faster 1-10)
var pauseit=1 //Pause marquee onMousever (0=no. 1=yes)?
////NO NEED TO EDIT BELOW THIS LINE////////////

var copyspeed=marqueespeed
var pausespeed=(pauseit==0)? copyspeed: 0
var actualheight=''

function scrollmarquee(){
if (parseInt(cross_marquee.style.top)>(actualheight*(-1)+8))
cross_marquee.style.top=parseInt(cross_marquee.style.top)-copyspeed+"px"
else
cross_marquee.style.top=parseInt(marqueeheight)+8+"px"
}

function initializemarquee(){
cross_marquee=document.getElementById("vmarquee")
cross_marquee.style.top=0
marqueeheight=document.getElementById("marqueecontainer").offsetHeight
actualheight=cross_marquee.offsetHeight
if (window.opera || navigator.userAgent.indexOf("Netscape/7")!=-1){ //if Opera or Netscape 7x, add scrollbars to scroll and exit
cross_marquee.style.height=marqueeheight+"px"
cross_marquee.style.overflow="scroll"
return
}
setTimeout('lefttime=setInterval("scrollmarquee()",80)', delayb4scroll)
}

if (window.addEventListener)
window.addEventListener("load", initializemarquee, false)
else if (window.attachEvent)
window.attachEvent("onload", initializemarquee)
else if (document.getElementById)
window.onload=initializemarquee

thanks 1DMF

It's ok I worked it out, the answer was staring me in the face (TT Whitepapers scroller).

Use

clearInterval(lefttime);

before calling the initializemarquee(); again, thanks TT
