No, that wasn't it. The problem I encountered was: run geomview, after
a second or two of doing nothing, it would calmly and quietly return
to the shell with no output whatsoever.  Upon looking at this with the
debugger, dde (our latest and greatest -- and sometimes buggiest --
debugger) would get very confused at some point just before the
application exitted. I couldn't see where geomview was even calling
exit(), dde was way off on the wrong line of source somewhere.

Seems like the Geomview code module in question had something to do
with lisp emulation.  I remember seeing something that made me think
it was a 10.20 OS quirk, but offhand I don't recall what that was.

Have you seen anything like this?

So I'd love to play with this more, but as I say my priorities have
been reset, and I'd rather wait for HPUX 10.20, and dde, and your
OpenGL port, and ESPECIALLY our OpenGL, to all settle a little more
before I put more time in on this.
