mc cons.saver not work for normal user

Subject: mc cons.saver not work for normal user

Hi.

I have one problem with mc. When I run mc as a root, everything
is ok. But when I try to run it as a normal user, subshell doesnt
save the content of the console ouput.

How to reproduce bug: I am in a blue panels and press ctrl-o to go to
the subshell. Run some commands, then ctrl-o back to blue panels, then
back to subshel via ctrl-o - the screen is completely black.

The  distribution is my own one based on a fedora core 4. In the
FC4 "normal" instalation everything works fine, even with a normal user.
Here is few messages:

# mc -V

Using system-installed S-Lang library with terminfo database
