Hoi

how come properties get los and function don’t?

```auto

MyXMLClass = function(){
	trace(this.ignoreWhite);
	trace(this.load);
}
MyXMLClass.prototype = new XML();
MyXML = new MyXMLClass

//trace: undefined
//trace: [type Function]

```

i want to use the ignoreWhite prop but it does not work :ninja:
