Thanks for your detailed reply.  I created a new script install on my
USB stick and now everything works fine - files are saved, configs
seem to be persistant.

I am writing this with mutt in inx.

Now I am on to importing my gpg keyring into inx.  I just want to make
sure that my keyring will not be compromised if it falls into the
wrong hands.

Thanks again
