Fooling onEnterframe ?!

1

Oke,

I’ve made a prototype for my mc’s.

MovieClip.prototype.knoppen = function() {
	this.onEnterFrame = function() {
		this.symall.hitTest(_root._xmouse, _root._ymouse, true) ? this.nextFrame() : this.prevFrame();
	};
};

using my mc’s in AS1 like this: sym01.knoppen(), sym02.knoppen() etc.

Working like a charm.

But I want a onRelease in my protoype. It should be like this

MovieClip.prototype.knoppen = function() {
	this.onEnterFrame = function() {
		this.symall.hitTest(_root._xmouse, _root._ymouse, true) ? this.nextFrame() : this.prevFrame();
	};
	this.onRelease = function() {
		this.gotoAndStop(15);
	};
};

Now my question. It keeps on “entering frame” so my gotoAndStop(15) won’t work. How can I prevent this from happening?
