ActionScript 2.0 :: Built In SharedObject Error With Browsers

On this website [URL] you will find a big flash applet at the top of the page. It has a sharedobject built in. Every time the applet goes to a new slide/scene (which it automatically does after x seconds), it updates the SharedObject so that once you refresh the page you end up at the same slide/scene again. Now the thing is that it does this only correctly in Internet Explorer.

Code:
var so=SharedObject.getLocal("pagehit");
if(so.data.pagehit != undefined){
/* Er bestaat al een cookie */
if(so.data.pagehit == "Scene 1"){
gotoAndPlay("Scene 1", 1);
};
[Code] .....

This is the code of Scene 1. Where you get forwarded to another scene if the cookie exist.
Code:
so.clear();
var so=SharedObject.getLocal("pagehit");
so.data.pagehit="Scene 2";
so.flush();
This is the code of the other scenes, ofcourse with a different scene number for each. It doesn't depend on the browser but on flash alone.
