Making a movie clip not behave like a button?

Hi i would like to make a movie clip not act like a button i.e i don’t want the finger to come up during roll over can anyone help, i have the following script on the movie clip so that the sprite animates and reverses on roll over

stop ();
this.onEnterFrame = function(){
if(rewind == true){
prevFrame();
}
}
this.onRollOver = function(){
rewind = false;
play();
}
this.onRollOut = function(){
rewind = true;
}

this.useHandCursor = false;
