Clicking Repeatedly on a Button without moving the mouse

Hey Guys,

So I might just be an idiot here but I can’t figure this out. I have a movie clip on the stage and when i click on it it fires a function.

Now if i repeatedly click on the button without moving the mouse, nothing happens. If i move the mouse a pixel to the left, then the function fires again.

Am i missing a property i need to enable or disable on the movie clip?

Thanks!
