I have a website using the prootype framework and I am looking to use a jquery plugin. Everything works just not in IE8. It works in ie7 which amazes me. Any idea what maybe wrong?

jQuery.noConflict();
function OpenUp(sURL){
  window.open(sURL,null,'height=560,width=820,status=yes,toolbar=yes,menubar=yes,location=yes,resizable=yes,scrollbars=yes',false); 
}
jQuery(document).ready(function($) {
 $("head").append("<link>");
 css = $("head").children(":last");

 css.attr({
   rel:  "stylesheet",
   type: "text/css",
   href: "/my/docs/jquery.simplyscroll.css"
     });

     $("#scroller").simplyScroll({
       autoMode: 'loop',
       framerate: 1,
       speed: 1
     });
});

I also tired the following: var $j = jQuery.noConflict(); var j = jQuery.noConflict();

everythig works just not in IE8 alone.
