Merci f.x0
Je sais qu'il est préférable d'ouvrir un nouveau post pour chaque nouveau sujet. Et je vais le faire si je ne trouve pas mon bonheur dans le lien que tu indiques.
Mais en même temps, je voulais attirer l'attention de Athox, qui a exactement le même PC que moi. (ACER aspire 9410)
Je viens de voir que je pouvait écrire un mail à Athox en passant par "Navigation/Liste des membres".
C'est ce que j'aurais dû faire dans un cas comme ça, évitant ainsi de polluer le forum par du hors sujet.
Mea Culpa et merci encore
