I have a flash file where I have a button with a mouse event and over it I have a movie clip. In AS2 I would write:

mc = null;

and the movie clip will still be there but I will still be able to interact with my button.

In AS3 this doesn’t work, does anyone know how to null an object to still interact with whats underneath?
