I ran some tests, and I'm sorry for asking a question that was easy to
answer. In case there are other people who want to use PostScript, I'll
share the outcome: in some PostScript macros I had variables called,
oddly enough, x, y etc. Miraculously, when x was changed to, say, xx, the
problem went away. It also disappeared when the variables were put in a
local dictionary. It seems that the PostScript commands in TeXtures affect
TeX storage area, due to the integration (TeXtures probably skips the
dvi phase altogether; that's why the problem didn't surface on the VAX,
where PostScript gets included by dvi2ps and is therefore isolated from
the TeX environment). I hope *someone* will be spared hours of frustration.
