Das Textfeld aktualisiert den Text nicht, das Nachrichtenfeld hingegen schon

Question

Ich verwende zwei Threads in dieser Anwendung, die ein Tron-Spiel ist. Ich habe eine TextBox, die den Spielstand am Ende eines jeden Spiels anzeigt. Jedes "Spiel" wird im 2. drawThread Thread gezeichnet.

Die Sache ist, ich zeige die Partitur in einer MessageBox die Zeile, nachdem ich die TextBox.Text ändern und die MessageBox zeigt die Partitur gut, aber die TextBox nicht.

Haben Sie eine Idee? Ich stelle sicher, Thread Safe Invokes zu verwenden (allerdings ändere ich den Text in dem Thread, in dem er erstellt wird). Der betreffende Code befindet sich in der createGame()-Methode und lautet

SetLabel(score);

public Form1()
        {
            InitializeComponent();
            canvas = game_panel.CreateGraphics();
            formCanvas = this.CreateGraphics();
            game_panel.Invalidate(true);
            bikes = new List<LightBike>();
            bikes.Add(new LightBike(new Point(game_panel.Size.Width - 25, game_panel.Height / 2), Color.Blue, "left", new DirectionKeys(Keys.Left, Keys.Down, Keys.Up, Keys.Right, Keys.Control)));
            bikes.Add(new LightBike(new Point(25, game_panel.Height/2), Color.Red, "right", new DirectionKeys(Keys.A, Keys.S, Keys.W, Keys.D, Keys.Q)));
            createGame();  
        }

        private void button1_Click(object sender, EventArgs e)
        {
            if (drawThread.ThreadState == ThreadState.Stopped)
            {
                InitializeComponent();
                createGame();
                drawThread.Start();
            }
            else
