Perhaps I should have been more specific. :) addstr (or any of it's brothers, even those bound to a subwin instance) write values to an internal buffer/object that then gets flipped (refreshed()) onto the physical screen. However. All of the routines I can find in the ncurses library want to take control of the "cursor" object. That is: they either want to advance it's position (addstr) or not (addchstr), but they both certainly grab "control" of it; at least, visually. Basically what I'm looking for is a way to refresh a portion of a curses-controlled "window" without affecting the current location of the cursor or having to manually move it and move it back. -- http://mail.python.org/mailman/listinfo/python-list
