hey David,
your suggestion works perfectly, it was my implementation that was breaking

Thanks again.

Thanks David,
For some odd reason if I do in my coopy
public function init():Void
{
trace("init in copy class");
}
it wont fire but it will fire the init method from the Original Class
(which by the way seem very similar to inheritance :) ).... any ideas why
this could be happening?
Thanks again...
