function isMouseLeaveOrEnter(e, handler) {
		if (e.type != 'mouseout' && e.type != 'mouseover') return false;
		var reltg = e.relatedTarget ? e.relatedTarget : e.type == 'mouseout' ? e.toElement : e.fromElement;
		while (reltg && reltg != handler)
			reltg = reltg.parentNode;
		return (reltg != handler);
