Cursor Help AS2

So I used a tutorial to make a neat little cursor animation....now the regular cursor is still visible. I would like to use another mc as the cursor. I'm really stuck I can get the cursor to hide but not my mc to show up. here's the code maybe someone could help me out

Code:

---

var i:Number = 0;


this.createEmptyMovieClip("canvas_mc",50);

var myListener:Object = new Object();
Mouse.addListener(myListener);

myListener.onMouseMove = function() {
        var t:MovieClip = canvas_mc.attachMovie("bubble","bubble"+i,canvas_mc.getNextHighestDepth());
        i++;
        t._x = _xmouse;
        t._y = _ymouse;
        t._xscale = t._yscale = (Math.random() *80) + 20;
}

Mouse.hide()
startDrag(MC_cursor,true)

if you need to see the file i've attached it

sometimes the cursor appears in flash even when you use the actionscript code to stop it. It usually appears when you right click.
