Bonjour!
Thanks!
NOw the issue 're figured out, "pinentry" 's necassary for PGP decrption in mail clients.But on VL7.1 , pinentry package 's missing still...Have to go slackware repo to grab it, once pinentry is installed, everything's back to normal and stable again with PGP mail clients now......
same issue encountered before with vl7.0 as well...
once pinentry installed, claws-mail 3.12 version sorce code's compiled from source install,running stable now
(claws-mail 3.9.3 pkg on VL7.1 repo doesn't support TLS, ssl protocol when pkg's compiled), but if modifying configure seetings of claws-mails, press save button, claismail soon went crashed, pressing apply button everything's normal...
at least claws-mail 's lightweighted in comparison to thunderbird...
pls. do upload some PGP key management tools to vl7.1 repo as well.
