Mouse tracking help

I have a movieclip on the stage that's acting as a mask with an instance name of 'mask_mc'. It's a 160x600 box.

I would like to have an onEnterFrame function, that tracks the mouse's Y position and sets mask_mc to that position value minus 160 (so the bottom of my mask lines up with the mouse).

I also was wondering if there's a way to track when the mouse has left the stage, and if so, have it automatically set the mask_mc to a given position, [0,-279].

I figured out how to get the mc to follow my cursor with this code...

Code:

---

this.onMouseMove = function() {
this.mask2_mc._y=_root._ymouse-600;
this.stripe_mc._y=_root._ymouse;
//trace(_root._ymouse);
updateAfterEvent();
};

---

Now I need to have the mc's snap back to a given spot when the user mouses out. Any help there?

You can't check if mouse has left screen in Actionscript 2.0, only in Actionscript 3.0

Put an empty movieclip on the bottom layer, and put an on enterFrame with an onRollOut=function(){
//Mouse is out of the movieclip, therefore is out of the stage, DO THIS
}

and onRollOver=function(){
//Mouse is over the movieclip, therefore is inside the stage, DO THIS
}

*I have not tested it, but it sh ould work.
