The reason for the problem is one of following:

S-Lang, ncurses and SystemV curses do support them, BSD curses

problem.

Midnight Commander can use ncurses as well as the display engine. However,
you may encounter minor differences, for instance, you will be unable to
force the color mode by giving the "-c" switch to GNU Midnight Commander.
As the last resort, you may try to use the curses library supplied with
your OS. Beware that some systems, e.g. SystemV Release 4, include the
curses library with bugs critical to GNU Midnight Commander. You may try
to recompile all your source code with the symbol BUGGY_CURSES defined,
