In JPanel sofort zeichnen

In JPanel sofort zeichnen - klappt nur ab dem 2n mal :-(

Guten Abend!
Um Java zu ueben habe ich ein kleines Spielchen angefangen. Ein Problem daran laesst mich momentan verzweifeln. Es geht um TicTacToe Variante. Als
Spielflaeche zeichne ich 9 (3x3) Felder, die extends JPanel sind. Mit
drawLine und drawOval zeichne ich entsprechende Symbole drauf.
Leider wird der erste Mausklick nach dem Spielstart ignoriert. Ignoriert insofern, dass es nichts gezeichnet wird. Die Methode springt an, variablen werden gesetzt, in der Console werden richtige Werte angezeigt, nur gezeichnet wird nichts. Ab dem 2n Klick geht alles in Ordnung. Sitze fast 4 Stunden davor und bringe es momentan zu gar nichts :confused:
Wisst Ihr einen Rat?

Zugegeben, der Code ist etwas wirr. Habe mir nicht viele Gedanken gemacht als ich spontan anfing :-(
 
Zuletzt bearbeitet:
Also ich hab das Programm mal getestet... und bei mir funktioniert alles wunderbar.
Spiel starten->Game->Player vs Computer->klick auf irgend ein schwarzes Feld... und es geht (und zwar beim ersten klick) :)
Woran das nun bei dir liegt... keine Ahnung hab den Code auch nur überflogen bin zu müde *grins* aber es geht ja auch.
