The function initscr() needs to be called before screen and window
functions only.  cbreak() and nocbreak() are not screen or window
functions so it shouldn't have to be called.  Calling endwin() does
call resetty() which does restore the terminal settings but nocbreak()
should take the terminal out of cbreak mode.  As far as why this
doesn't work...  I dunno;  I have found problems like this before with
curses and terminal modes and have managed to avoid them but never fix
them.
