Kirupa tutorial draggable menu 2

Hey,
I was doing this draggable menu 2 tutorial (http://www.kirupa.com/developer/flash5/menudragger2.htm) and i found a problem…

At the end it shows u how to change a function (that is in a onClipEvent(load)) to a prototype. So i try to do that and the prototype doesnt work…
Everything works fine before the prototype.
I copy paste the prototype AS to the first frame in the timeline. Also i tried copy pasting the AS from the finnished file that u can download, and it doesnt work either.
Does flash mx 2004 has problems with prototypes or soemthing? Im cluesless why my prototype, which is an exact copy of the tutorial and the working file of the tutorial, doesnt work.

Any clues anyone?
