Loader bar strange behaviour in certain browsers

Question

Hi there,
I've been using this code for loader bars for a little while and it looks good. Most of the time !
In some browsers (notably chrome mac, and firefox PC) the loader bar flies off in the opposite direction and doesn't show the load at all, just puts a white bar across the left hand side of the page (from the origin of the movieclip backwards) !
Here is my code, can anyone help me out please ? :-
var myMovie:Sprite;
var l:Loader = new Loader();
l.contentLoaderInfo.addEventListener(ProgressEvent.PROGRESS, loop, false, 0, true);
l.contentLoaderInfo.addEventListener(Event.COMPLETE, done, false, 0, true);
l.load(new URLRequest("myswf.swf")); // << Full URL on export
function loop(e:ProgressEvent):void
  var perc:Number = e.bytesLoaded / e.bytesTotal;
  logo.bar_mc.scaleX = perc;
  logo.bar_mask.scaleX = perc;
function done(e:Event):void
  removeChild(logo);
  logo = null;
  myMovie = Sprite(l.content);
  stage.addChild(myMovie);
  l.contentLoaderInfo.removeEventListener(ProgressEvent.PROGRESS, loop);
  l.contentLoaderInfo.removeEventListener(Event.COMPLETE, done);
  l = null;
Thanks in advance

clear your cache and test.  if the problem never occurs with a cleared cache then your swf may be loading from cache before a progressevent is dispatched.
if that's the issue, handle in your complete listener function.
