ActionScript 3.0 :: Unable To Use Scrollpane Component Cross-browser

I made an as3.0 website in Flash cs4. [URL]The content of the pages is placed in a ScrollPane component, that comes with cs4. It all works fine in Chrome, Opera and IE but Firefox and Safari only show the top-left 100x100px.

Here's how it works.index.html holds a variable that tells my flash where to go (agenda, djs, bookings etc.). index.html loads preloader.swf via swfObject. Preloader.swf loads theKitchen.swf and passes a variable to it so it knows where to go, and triggers the init() function.

Code:

var loader:Loader = new Loader();
var go:String;
public function Preload():void
{

[code]...

In the "mainswf" then comes some if/else statements to build the desired page. If you click a button in the menu a function is triggered with an if/else statement that checks if the page that belongs to that button isnt allready shown. If its false the source of the ScrollPane is set to that page.Every page is build in a seperate class. The class ready an XML file that holds all the text/urls to images/ video.
