I always have to check the manpage to keep these straight.
If you're using subwin rather than newwin, that's likely the
problem:

       Calling subwin creates and returns a pointer to a new win-
       dow with the given number of lines, nlines,  and  columns,
       ncols.   The  window  is at position (begin_y, begin_x) on
       the screen.  (This position is relative to the screen, and
       not to the window orig.)  The window is made in the middle
       of the window orig, so that changes  made  to  one  window
       will  affect  both  windows.   The subwindow shares memory
       with the window orig.  When using this routine, it is nec-
       essary  to call touchwin or touchline on orig before call-
       ing wrefresh on the subwindow.
