Dead simple, stupid question

simple, ive got this…

_root.mySound = new Sound();
_root.mySound.loadSound(“intro.mp3”, true);
_root.mySound.start();

however, i want the flash to pause until the sound clip has loaded (the sound accompanies the visuals). either I should use other means of achieving this (different way of loading music), or some sort of while/if loop.

any help is much appreciated.
