Detectar mouse con Flash

Código Flash

onClipEvent (load) {
    // in miliseconds
    stillFor = 3000;
    startTime = getTimer();
}
onClipEvent (mouseMove) {
    time = 0;
    startTime = getTimer();
}
onClipEvent (enterFrame) {
    time = getTimer()-startTime;
    if (time>=stillFor) {
        time = 0;
        startTime = getTimer();
        // your code here
    }
}
stillFor is a variable which sets the duration we want the mouse to be still for before executing our code.
