Summary: Random NullPointerException

Initial Comment:
I occasionally randomly get a nullpointer exception, I think it is a threading 
issue since it ussualy happens if I change the molecule I am showing before it 
finishes displaying another one. I am using jmol 11.8.9.

Stacktrace:
java.lang.NullPointerException

Message:
 I see you are using openStringInline. That's not queued, and it could be
causing the problem. I'll look into that. It would be nice to get this to
be reproducible.
