In "Change timestamp" screen, choose the dates to update :

If you have few custom settings, you can rename your xnview.ini file to xnviewini.old before starting XnViewMP.
A new xnview.ini will be created... and perhaps the problem will be solved

Des réglages non permanents, ça me ferait penser à un problème de droits ... (Windows permet-il la mise à jour du fichier xnview.ini ?)
