Interval not clearing? Why?

I am having a problem with this code and I believe it is because the intervals are not being cleared and all the functions are running through over and over. I am not sure how to fix this as this code is a bit beyond what I would have come up with on my own (this was built from an example provided by Stringy) and also worked…exactly as it is… in the past.

The problem began when I moved from Flash MX 2004 Professional to Flash 8. As long as it is saved and exported (or published) as a Flash MX 2004 file, the code works. Save it as a Flash 8 file and it does not. Unfortunately, I saved the only file I have in 8 format before discovering this.

Actionscript 2.0 was introduced with MX 2004, (correct?) so this should not have anything to do with the problem…

//sets up mc holders and fades pics in and out
var i = 1;
function loadIn(movie, x, y) {
	**clearInterval(arguments.callee["Interval"+i]);**	clip = _root.createEmptyMovieClip("holder"+i, i+20);
	clip._x = x;
	clip._y = y;
	clip.loadMovie(movie);
	clip._alpha = 0;
	_root["temp"+i] = _root.createEmptyMovieClip("tmp"+i, i+10);
	_root["temp"+i].obj = clip;
	_root["temp"+i].onEnterFrame = preloadf;
	i++;
}
function preloadf() {
	var e = this.obj.getBytesLoaded();
	var f = this.obj.getBytesTotal();
	if (f == e && f>4) {
		this.onEnterFrame = fadein;
	}
}
function fadein() {
	this.obj._alpha += 4;
	if (this.obj._alpha>=100) {
		this.onEnterFrame = fadeout;
	}
}
function fadeout() {
	this.obj._alpha -= 2;
	if (this.obj._alpha<=0) {
		this.obj._alpha = 0;
		delete this.onEnterFrame;
	}
}
loadin.Interval1 = setInterval(loadIn, 1050, "intro1.jpg", 555, 112);
loadin.Interval2 = setInterval(loadIn, 2050, "intro2.jpg", 191, 112);
loadin.Interval3 = setInterval(loadIn, 3050, "intro3.jpg", 0, 112);
