>Description:
I'm running a mutt instance in screen and pipe a mail through an external 
program (e.g., less(1)) via the '|' key. I then interrupt the external program 
with CTRL-Z. On the shell prompt, I type "fg", but do not get back in the 
external program. A second CTRL-Z and "fg" gets me back to the external program.
I also tried using /bin/ksh as EXECSHELL, but I got the same behaviour.
