Stopwatch, how do I stop it?

Hi, I am having trouble with timers running different on different computers, this one seems to run the same on different ones. But I don´t get how to stop it. Grateful for help, should be a piece of cake for you AS geniuses. Thanx in advance!


onEnterFrame = function () {
    time = getTimer();
    miliseconds = time;
    minutes = Math.floor(miliseconds/1000/60);
    miliseconds -= minutes*1000*60;
    seconds = Math.floor(miliseconds/1000);
    miliseconds -= seconds*1000;
    miliRound = Math.round(miliseconds/10);
    min = (minutes<10 ? "0" : "")+minutes;
    sec = (seconds<10 ? "0" : "")+seconds;
    ms  = (miliRound<10 ? "0" : "")+miliRound;
    textbox.text = min+":"+sec+":"+ms;
};
