Does onEnterFrame stop buttons from working?

1

I used kirupas tutorial ‘Complex Button RollOver/Rollout Effects’ to make a menu that slides down when you roll over it. I have buttons inside that menu_mc - but they dont work.

My question is - does the on enter frame function prevent buttons from working?

Here is the code that is inside my menu_mc:
stop();

this.onEnterFrame = function(){
if(rewind == true){
prevFrame();
}
}

this.onRollOver = function(){
rewind = false;
play();
}

this.onRollOut = function(){
rewind = true;
}
