用mouse_event发送鼠标位移，位移几次以后程序卡死。关闭不了

Question

功能是按下鼠标左键以后鼠标位移：
private void mh_MouseDownEvent(object sender, MouseEventArgs e)
{
if (e.Button == MouseButtons.Left)
{
//timer1.Enabled = true;
//timer1.Interval = Mv_data.PL;
if (MainOFF == true && TIMEOT_TAB == true && RESET == false) //单点位移
{
mouse_event(MOUSEEVENTF_MOVE, 0, Mv_data.DD, 0, 0);

            }
            //MSCK.NMouseMoveR(Mv_data.DD);
            LeftTag = true;


        }
                    }

                    鼠标钩子初始化：
                            private void MouseHookInit()
    {
        mh = new MouseHook();
        mh.SetHook();
        mh.MouseDownEvent += mh_MouseDownEvent;
        mh.MouseUpEvent += mh_MouseUpEvent;

        //mh.MouseMoveEvent += mh_MouseMoveEvent;
    }


            鼠标钩子
             class MouseHook
{
    private Point point;
    private Point Point
    {
        get { return point; }
        set
        {
            if (point != value)
            {
                point = value;
                if (MouseMoveEvent != null)
                {
                    var e = new MouseEventArgs(MouseButtons.None, 0, point.X, point.Y, 0);
                    MouseMoveEvent(this, e);
                }
