Does anybody know what this is all about?

 it's for git (version control), 'git commit' uses a terminal editor like nano
if yr using the version control then set the env in your system startup

$  export EDITOR="nano"

(i thought the message was a bug that got fixed so might not be on all gambas versions)

 Thanks, Bruce. That makes sense. Getting rid of the .git folder stopped the message. I'm using Gambas 3.16.2 Stable.
