Ben,
  I have a special build for MacOS X that should avoid this problem.
The normal MacOS X builds make significant use of the core services
and carbon frameworks, which seems to result in contacting the windowing
system even when we're not really using it. If I build a MacOS X version
of VMD against the X11 libs, or with a text-only build, I can produce
a binary that doesn't encounter this problem. If you would like to try
a VMD 1.8.7 test version that's build this way, let me know.

Cheers,
  John Stone
