This.onMouseInactive <-- ? or something like it

I am attempting to have a mc fade in onMouseMove and fade out once the mouse becomes inactive.


close_mc._alpha =0;
mouse_timeoutMS = 2000;
this.onMouseMove = function() {
	clearInterval(itvMouseID);
	this.onEnterFrame = function() {
		if (close_mc._alpha<100) {
			close_mc._alpha += 10;
		}
	};
	if (close_mc._alpha == 100) {
		delete onEnterFrame;
		itvMouseID = setInterval(fade_out, mouse_timeoutMS);
	}
};
fade_out = function () {
	clearInterval(itvMouseID);
	this.onEnterFrame = function() {
		if (close_mc._alpha>0) {
			close_mc._alpha += 10;
		}
	};
	if (close_mc._alpha == 0) {
		delete onEnterFrame;
	}
};
