A real "googly"? (I like that!)
Without trying it myself, I will guess that it will work. But
inadvertantly, you have created an insidious bug. Since you have
define an "on new" handler in a movie script, you have now
overwritten Director's real "new" handler. The problem is that you
cannot now call the new function in Director create new things like
bitmaps, scripts, cast members, xtras, etc. (Try creating a second
script like this where you intend it to be a parent script, but make
it a movie script - does it instantiate an object of your second
type??)
I have done this by accident many times and have learned that this is
a very bad thing. If you want it to be a parent script - make sure
that you set its type to be a parent script.
