Bonjour à tous,

suite a des infections de spy et autres virus j' ai du effectuer un nettoyage complet .

il m' est impossible d' en mettre un que ce soit par definir en tant que arriere plan ou par le gestionnaire.
d' ailleur pour ce dernier les images n 'apparaissent plus en previsualisation.

je ne peus que changer la couleur de l' arriere plan et c' est tout.

merci de votre aide............
