Problem onRollOut

I have a simple scroller that scrolls up or down as the user moves their mouse. The problem is that when you RollOut the scroller keeps moving. I can’t figure out how to put a onRollOut function that will stop the scroll upon RollOut. Can you help?

years.onRollOver = yearsOver;

function yearsOver() {
this.onEnterFrame = yearsPanel;
delete this.onRollOver;
}

function yearsPanel() {
if (_xmouse<b.xMin || _xmouse>b.xMax || _ymouse<b.yMin || _ymouse>b.yMax) {
this.onRollOver = yearsOver;
delete this.onEnterFrame;
}
if (years._y >= 80) {
years._y = 80;
}
if (years._y <= -90) {
years._y = -90;
}
var ydist = _ymouse -170;
years._y += Math.round(-ydist/7);
}

var b = stroke.getBounds(_root);
