I have a function that tells a movie clip to hover around, how do i turn it off though?

Question

on roll over? I'd like to have it so that when you roll over
an invisible button over the movieclip, it will stop the motion
created by this function.
HOW is this done? I mean, I can call a function, but how can
I stop it? And then restart it when you roll off the invisible
button.
The following code is on frame 1 of my file....
Please save from this hellish problem....Thanks.
function floatMc(float_mc:MovieClip, range_num:Number,
frames_num:Number):Void {
var xMin:Number = float_mc._x-range_num;
var xMax:Number = float_mc._x+range_num- 7;
var yMin:Number = float_mc._y-range_num ;
var yMax:Number = float_mc._y+range_num - 14;
var frames:Number = frames_num;
//number of seconds for the tween to take, and how often to
start a new tween
var me:MovieClip = float_mc;
function newTween() {
//adjust the easing class as needed
var xNew:Number = (Math.random()*(xMax-xMin))+xMin;
var yNew:Number = (Math.random()*(yMax-yMin))+yMin;
xTween = new mx.transitions.Tween(me, "_x",
mx.transitions.easing.Regular.easeInOut, me._x, xNew, frames,
false);
yTween = new mx.transitions.Tween(me, "_y",
mx.transitions.easing.Regular.easeInOut, me._y, yNew, frames,
false);
var IntID:Number = setInterval(newTween, (frames*(1000/31)));
floatMc(penthouse, 12, 72);
floatMc(midnight, 12, 82);
floatMc(photo, 12, 62);
floatMc(meeting, 12, 66);
floatMc(everything, 12, 80);
floatMc(space, 12, 77);
