Why doesn't this work inside a MC?

So this draggable menu thing works well on it’s own.
But when inside a Movie Clip it goes nuts?

WHY?

I think you have a timeline issue, but I am not sure. I’ll bump this though as it is somewhat interesting.

Also, I should say that I tried to modify the paths of the script to work inside the MC (instance name of “mainbox”).

I thought I had done it all but it still wasn’t quite right. So I included the .fla in it’s original unmodified form.
