es raro pero lo has probado asi
Código PHP:
loadMovie("editorial.swf", _root.center_mc.container.myContainer);
_root.center_mc.container.myContainer.stop();
this.onEnterFrame = function() {
if (_root.center_mc.container.myContainer.getBytesTot al()>1) {
percent = int(_root.center_mc.container.myContainer.getBytes Loaded()/(_root.center_mc.container.myContainer.getBytesTot al())*100);
text_info.text = percent+"%";
bar_mask._xscale = percent;
if (percent>=100) {
delete (this.onEnterFrame )
_root.center_mc.container.myContainer.lockroot=true// si no funciona elimina esta linea y prueba de nuevo
_root.center_mc.container.myContainer.play();
}
}
};
