Xml browser bug. very odd

Hi All
Am just banging my head against the wall trying to figure out why this is pulling the xml data in locally and on some computers and not on others when stored on the server.
for example
my FF3.0.3 and IE7 work fine with flash player 9
my coleauge can view in IE7 flash player 9 but not in FF flash player 9

This issue has a 50% fail rate very odd.

Is my method causing issues here or something.

any help would be much appriciated.


//---------loading the external xml file-------
var urlRequest:URLRequest = new URLRequest("http://ir1.euroinvestor.com/asp/ir/xmlirmultiiso2.aspx?companyid=2811234");
var urlLoader:URLLoader = new URLLoader();
var myXML:XML = new XML();
var xmlList:XMLList;
myXML.ignoreWhitespace = true;
urlLoader.addEventListener(IOErrorEvent.IO_ERROR, onIOError, false, 0,


function fileLoaded(event:Event):void {
    myXML = XML(event.target.data);
    xmlList = myXML.children();
   DATATXT.text = xmlList.child(6)+"p";

	function onIOError(evt:IOErrorEvent):void {
DATATXT.text = String(evt);
