I would say that this (particular) curses bug is only found in the SCO
and IBM distributions.  I tried it on Tandy Xenix (1.0) which is roughly
equivalent to SCO 2.2 (286 version) which is based on the Microsoft base
with some AT&T copyrights.  Both bugs 2 & 3 worked without any of the
problems that have been reported.

What I have seen in some curses implementations is the need to do a
refresh() before and after and stand[end|out] mode, otherwise the
command would not seem to have any affect.  So I was plesantly surprised
that these 2 code fragments ran without any difficulties.

It must be something in the console driver specific to the SCO and IBM
distributions (Did IBM use SCO as a distribution base?).
