private function tracePath (dispObj : DisplayObject, s : String = "") : void
{
	if(dispObj.parent != null)
	{
		tracePath(dispObj.parent, s + "." + dispObj.name);
	}
	else
	{
		var a : Array = s.split(".").reverse();
		var output : String = "";
		for (var i : Number = 0;i < a.length; i++) 
		{
			output = output + "." + a[i];
		}
		trace("PATH: " + output.substr(1, output.length - 2));

    }
    if(DObj.parent == DObj.root) {
    // we have arraived at the stage return the path;
    Arr.reverse();
    return Arr.join(”.”);
