[Résolu] Bugs graphiques avec Python et PyGTK
Hello,
à la suite de ce post : http://forum.ubuntu-fr.org/viewtopic.php?id=61019
où je présente mon programme de téléchargement de musique sur RadioBlogClub, j'aimerais bien un peu d'aide pour m'aider à corriger les bugs graphiques !
J'ai remarqué que souvent, au deuxième téléchargement, le changement de bureau ou l'utilisation de l'ascenceur fait planter le bouzin.
