JTabbedPane : Problème de focus ?

Bonjour à tous,

Besoin d'un ptit coup de main car je suis un peu noyé dans le code.

IDE : Net Bean - Utilisation de l'outil design
Objet : Interface Graphique

Je travaille avec un JTabbedPane comme père et des JPanel comme fils, la navigation se fait par onglet.

Au lancement (phase d'initialisation) de l'ihm (Premier onglet selectionné par default - Premier JPanel), j'ai un petit soucis de focus (je pense).
Les différents JPanel se mélangent, c'est à dire que par exemple les boutons d'un autre onglet (Autre JPanel) sont sélectionnable sur le premier JPanel. Conclusion c'est moche et rend l'application instable.

Autre phénomène quand je clique sur un autre onglet et je reviens au premier, le problème à disparu et le premier Jpanel à bien le focus.

Voilà, je ne sais pas si vous avez bien serné le problème. Si non, je tenterai de le reexpliquer plus clairement.

J'ose mette le code générique, généré par l'outil design de NetBean :
