I try to install 1.4b versión but it sais that is not compatible
1.3 version shows this error:
Version 1.0b9 of the Free/Busy addon did not store passwords correctly. The addon will now perform a one time operation to move the password for ftp://ftp.company.com/freebusy/myuserid.ifb into the PasswordManager. You may be prompted by the application to unlock the password manager.
I configure the settings (free busy url) and when I try to invite someone to a meeting it crashes

Questa recensione riguarda una versione precedente (1.3) del componente aggiuntivo.
