 6.6 When I use Ctrl-O I don't get a subshell. How do I fix this? Only bash, tcsh and zsh can be used as subshell. Use one of those shells as your default shell, and it will be used as subshell in GNU Midnight Commander.

6.7 Ctrl-O doesn't work at all. What happens? Ctrl-O works if either the subshell is used or the terminal can save the output of the commands so it can be restored. If neither is  true, there is absolutely nothing interesting behind the panels!

Only few terminals support screen saving. It's xterm, rxvt and other xterm-like terminals and virtual terminals on Linux and FreeBSD.
