[ fragmented even more]
% program 'A'
%     initscr();
%	      system(...program 'B'...);
%     endwin();

% program 'B'
%   initscr();
%   ...do various things...
%   endwin();

My curses manpage says "Programs desiring shell escapes or suspending with
control Z can call resetterm before the shell is called and fixterm after
returning from the shell."

I assume the same would apply for system() (which is, essentially, calling
a shell).

I found out from another curses question in comp.unix.questions that
curses for System V is different from curses for BSD so your mileage
may vary (although I'm on a SysV machine, whose manpage refers to
"ctrl-Z", a BSD-ism).
