Hey,  
How can I use setInterval to start and stop the root timeline? I would like to use it in this little fade function wherein the setInterval would kick into effect once the alpha is 100%. You can see where I think it needs to go. Here’s the code.

```auto
stop();
variable = x+5;
title_mc._alpha = 0;
function fade() {
	var nFadeSpeed = 4;
	if (title_mc._alpha>100) {
		delete this.onEnterFrame;
		setInterval(nextFrame, 10000);
	}
	title_mc._alpha += nFadeSpeed;
}
onEnterFrame = fade;

```

Please and thank you!
