Disabling buttons

So I’ve been creating this menu that loads an animation through the loadMovieNum() command when one of the buttons in the menu is pressed. However, I’d like to disable the menu while that animation is running.

I first tried loading a false menu over the real menu (I put a new menu that had the buttons changed into graphics on layer 90) but the buttons underneath still reacted. I even tried putting a solid object (Just a solid rectangle to make sure I was really over the menu) over the menu, and while the buttons then couldn’t be seen, they still reacted to the mouse rolling over them.

Is there a simple way to disable the buttons while the animation loads and then re-enable them once it’s finished?
