With the help of Michael I figured it out.  It turns out that I did
change the Ps/Pe macros slightly, but had forgotten.  The old version
used to set ps, vs, nf, and the font in the new environment each time
it was called.  In the newer version I just set up the environment once
at macro load time (it's the programmer in me--I can't help it).
Thus if a font change is made in the old version, it gets reset.  In the
new version, it stays with the environment.

Should I change it back to the old way?  Michael has already fixed his
markup, but changing back to the old way won't break that and may prevent
others from having the same problem.
