>From the ncurses man page:

       Note that curses  does  not  handle  overlapping  windows,
       that's  done by the panel(3X) library. This means that you
       can either use stdscr or divide the screen into tiled win-
       dows  and  not  using  stdscr  at all. Mixing the two will
       result in unpredictable, and undesired, effects.

In other words, you *can* have two windows that overlap (such as
stdscr and a subwindow), as long as you only draw on, and refresh, one
of them.

For my part, I've generally found it simpler to just use stdscr and
calculate the coordinates of subregions in the code, or to go all the
way and use panels. Using tiled subwindows usually makes for more
complicated code in the end.
