Ladislav responded well to most questions (thank you!) but I’ll add some info as well.
4) The reset password is greyed out when you are signed because it does not make sense to RESET your password when you know the old one. Then you do a password CHANGE.
6) We decided to do the auto-upgrade to version 1 by default, because this works well for most users. Before we did that, we had a lot of questions why a password was required twice all the time (which happens when the AxCrypt 2 sign in password is different from the AxCrypt 1 file password).
