put a movieclip on your stage.
give it the instancename 'dragger'
then put this code on a frame that spans the first 100 frames (or howerver many frames you want to scroll thru) of your movie....
Code:
dragger.onPress=function(){
this.startDrag(false,1,this._y,100,this._y);// drag from 1 to 100
this.dragging=true;
this.onEnterFrame=this.whileDragging;
};
dragger.onRelease=function(){
this.dragging=false;
this.onEnterFrame=null;
};
dragger.whileDragging=function(){
_root.gotoAndStop(Math.floor(this._x));
};
