XML.onLoad works at Flash 8 But is not working in Flash CS3

Hi,

I want to load a XML file using ActionScript 2.0 with Adobe Flash CS3 but onLoad event of XML object doesn’t fired. While the same code is working in Mocromedia Flash 8. Here is my code:

 
var xmlFile:XML = new XML();
xmlFile.onLoad = function(success) {
 trace("salam"); 
}
xmlFile.load("player.xml");

I suspend that this cause from new Security Manager that is designed in Flash CS3. In the “Setting > Publish Setting > Flash > Local Playback security” I choosed “Access local files only”. Also I’m testing the movie at the Flash player itself in a Windows machine and not in the Browser.
Do some of you gues have the same experience with Flash CS3?
