While designing a website, i added a preloader so that there’s a loading bar that displays while the website is loading. The code for it is just standard one. However, i encountered a really weird bug:

After loading the main swf and adding it to the screen, there seems to be a few frames that were skipped. And even weirder, if i hit the refresh button of my browser, everything seems became ok and no frames were skipped O\_o  
Check out [http://www.burnwater.com.ph/projects/bluemedia/](http://www.burnwater.com.ph/projects/bluemedia/) for the said problem.

Any guesses and suggestions on how to fix it? X\_X I dont think there’s anything wrong with my preloader. Here’s the code just in case:

var myRequest:URLRequest = new URLRequest(“main.swf”);  
var myLoader:Loader = new Loader();

myLoader.load(myRequest);

myLoader.contentLoaderInfo.addEventListener(Event.OPEN,showPreloader);  
myLoader.contentLoaderInfo.addEventListener(ProgressEvent.PROGRESS,showProgress);  
myLoader.contentLoaderInfo.addEventListener(Event.COMPLETE,showContent);

var myPreloader:Preloader = new Preloader();

function showPreloader(event:Event):void {  
addChild(myPreloader);  
myPreloader.x = stage.stageWidth/2;  
myPreloader.y = stage.stageHeight/2;  
}

function showProgress(event:ProgressEvent):void {  
var percentLoaded:Number = event.bytesLoaded/event.bytesTotal;  
myPreloader.loading\_txt.text = "Loading - " + Math.round(percentLoaded \* 100) + “%”;  
myPreloader.bar\_mc.width = 198 \* percentLoaded;  
}

function showContent(event:Event):void {  
removeChild(myPreloader);  
addChild(myLoader);  
}
