I've been using screen for a while and its basic features suit my needs
well. However, when running alpine from within screen, I have an issue
when I try to launch the external viewer. It tells me that the command
completed, but nothing happens. If I do the same thing from a regular
session or tmux it works just fine. And if I run tmux inside screen and
alpine inside that then it works just fine.
If I try to pipe a message to a file I get an error "can't exec (script)
no such file or directory"
