Alpine viewer issues

Hi,

I posted this question at
http://unix.stackexchange.com/q/31243/5788

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"

Any help would be appreciated!
Thanks,
Wayne
