Same SWF Frame 1 Preloader will not show up until 84%

programming flash
1

Well, since it is all supposed to be one SWF file, I’m doing all the preloading in Frame1.

I have a simple textField on the stage which displays the percentage, and this code every frame:

stop();

import flash.events.ProgressEvent;

// Check if already loaded
if (this.loaderInfo.bytesLoaded == this.loaderInfo.bytesTotal )
    { this.nextFrame(); }
else
{
    this.loaderInfo.addEventListener(ProgressEvent.PROGRESS, update);
    function update(e:ProgressEvent):void
    {
        if (e.bytesLoaded == e.bytesTotal)
        {
            this.loaderInfo.removeEventListener(ProgressEvent.PROGRESS, update);
            this.nextFrame();
        }
        else
        {
            percentText.text = Math.floor( (e.bytesLoaded*100)/e.bytesTotal ) + "%";
        }
    }
}

Sadly, the textField will not show up until the SWF is loaded to about 70%.

Is there any reason why, and any workaround?
