Hm... einen Fehler hab ich schon selber gefunden. Ich hatte noch eine paint-Methode im Applet, die den Hintergrund zeichnet. Jetzt sieht man die Komponenten alle, allerdings sehe ich den Hintergrund nicht. Wenn ich jedoch an dem Fenster, in dem das Applet läuft, "ziehe", erscheint der Hintergrund. Ich hab schon versucht ein repaint() einzufügen aber das hilft auch nicht.

In der getSudoku()-Funktion funktioniert das Sysntax-Highlighting nicht richtig...
