FileReference ProgressEvent

Question

Hi,
After scratching my head for months about a ProgressEvent issue I decided to post my problem.
I've been searching the web for a long time about my problem and all I could find was people with similar problems..
But none of them had a solution.
I've created a SWF file to upload files to the web server.
The even triggers the progressEvent.PROGRESS to let a javascript function know when the progress has changed.
When it's done uploading it triggers Event.COMPLETE.
When I test my code at first it doesn't seem to work.
The progress is event 2 or 3 times and then claims it's finished (While the Event.COMPLETE isn't fired yet).
When the file is actually uploaded flash triggers Event.COMPLETE accordingly.
So Event.COMPLETE is correct.. but ProgressEvent.PROGRESS is not.
At least, thats what I thought, when I tested it on another pc (With windows XP 64bit) it worked (Magically?)
I tried it on a Mac and it, again, worked...
I myself am using Windows 7 Professional 64 bit.
Could anyone guide me and tell me why it behaves like this?
Below is my code as it is right now.

                    ExternalInterface.call("uploader.report", "Step 2.1 - Adding files to realList");
                    realList.push(file.fileList[i]);
                    var name:String = file.fileList[i].name.toString();

               colorTransform.color = 0xff0000;
               browseBtn.transform.colorTransform = colorTransform;
               /** No files to be uploaded **/
               if(realList.length <= 0)
                    ExternalInterface.call("uploader.report", "Step 3 - No files found");
                    return;
               /** Create an url request **/
               var url:URLRequest = new URLRequest(t);
               /** Start uploading **/
               for(var i:int = 0; i < realList.length; i++)
                    realList[i].addEventListener(ProgressEvent.PROGRESS, handleProgress);
                    realList[i].addEventListener(Event.COMPLETE, handleComplete);
                    realList[i].upload(url);
                    ExternalInterface.call("uploader.report", "Step 3 - Uploading files");
          private function handleProgress(e:ProgressEvent):void
               ExternalInterface.call("uploader.report", "Step 3.P - Sending progress report:");
               ExternalInterface.call("uploader.report", e.currentTarget.name);

               for(var i:int = 0; i < realList.length; i++)
                    realList[i].addEventListener(ProgressEvent.PROGRESS, handleProgress);
                    realList[i].addEventListener(Event.COMPLETE, handleComplete);
                    realList[i].upload(url);
          private function handleProgress(e:ProgressEvent):void
                        /** Update text fields with the bytes **/
               prgrs.text = e.bytesLoaded.toString();
               ttlsize.text = e.bytesTotal.toString();
          private function handleComplete(e:Event):void
There's the code.
My problem is that when I'm running this code, the progress jumps to 50%, then to 100% (even when the file is no where near finished)... After a while Event.COMPLETE is fired.
When others (3 other people) run it, the progress increases progressively (yep) and when its done it fires Event.COMPLETE accordingly (so everything goes well on their run).
