I've deleted the program, installed it again, created again my mail accounts. After giving the link to the folders containing my mails/settings ... it works. Don't know what happens with my previous configuration.
Note that I've lost my adress book .. it seems that it was store in the default folder (For Win 2k/XP => X:\Documents and Settings\User\Application Data\Mozilla\Profiles\default\xxxxxx.slt\) Is there a way to store it elsewhere ? (e.g. in the folder where the mails are stored?)
