Hello netters,

I'm having a weird problem with curses on an IBM 530 RS/6000 running
golden code.  I've tried to reduce the problem to its essentials in the
small test program included below.  Basically, the program works when I
include curses.h and link to -lcur.  However, one is supposed to use -lcurses
with curses.h.  This is what I'd prefer to do, as -lcurses includes such
niceties as box, wattron, and wattroff.  The problem I have when I link to
-lcurses is that stuff written to the right edge of the screen gets shifted
over to the left by one character.  Here's sample output from the program that
works:

$ testc
                                                                           +   +

                                                                           12345
                                                                           
                                                                           +   +

This program writes the top line OK, but the rest of the stuff is shifted
over to the left by one character:

$ testc1

                                                                           +   +

                                                                          12345

                                                                          +   +

Thanks for any help.
