problems loading external swf

I'm having a path-related problem, only I'm not sure what it is. I have a swf that essentially pans & zooms:

Code:

---

onEnterFrame = function() {
        S = (slider._y - 25) + 100;
        w0 = map._width;
        h0 = map._height;
        map._xscale = map._yscale = S;
        w1 = map._width;
        h1 = map._height;
        map._x -= (w1 - w0)/2;
        map._y -= (h1 - h0)/2;
        restrictMovement();
}

---

Every frame, it checks the slider's position, and re-calibrates the _x and _y to retain the center when the map is being zoomed. I then call restrictMovement() which checks the bounds and makes sure the map doesn't scroll out of the viewing area.

The problem is, when I call use MovieClipLoader.loadClip() on this swf, it no longer calls the restrictMovement() function. Any idea why? (The zoom still works, and it still re-calibrates the _x and _y so I know it's using the onEnterFrame event, it's just not calling the function)

Or perhaps there's something wrong in restrictMovement()?

Code:

---


function restrictMovement() {
        xMin = -map._width + win._width;
        yMin = -map._height + win._height;
       
        if(map._x < xMin) {
                map._x = xMin;
        }
        else if(map._x > 0) {
                map._x = 0;
        }
       
        if(map._y < yMin) {
                map._y = yMin;
        }
        else if(map._y > 0) {
                map._y = 0;
        }
}

Any help would be appreciated.
