Hi Bob,
This is helpful as I wasn’t sure if I understood the intent.
I’ll do some more testing with my app in the next day or so to make sure that I
can reproduce what I’m seeing and create a generic example. There is still a
pretty good possibility that the bug is in my code.
The first larger molecule would be something like 2B9N, so there are a lot of
atoms to move during any particular rotation rendering thread loop. My guess
was that rotation was on a separate thread and what was happening was that
after the zap a new rotation thread was created for the second smaller
molecule, but the first larger molecule thread continued for a while. Jmol was
rendering the second smaller molecule, but the smaller molecule’s zoom and
rotation were jumping around. After things settled down, the second smaller
molecule’s rendering and positions seemed correct. That’s what led me to ask
the question.
It kind of looks like both rotation threads are taking turns writing to the
active second molecule’s rotation/position data after the zap, but before the
first rotation thread dies.
I’m pretty well tooled up to debug this if you’ll give me a hint about where to
look and generally how it works.
Thanks,
—Chuck

It's definitely supposed to stop. The rotation is a separate process, so it is
supposed to be continuing after the script is "finished". I'm not able to
reproduce your problem. -- Can you put up a page that illustrates that?

Issue: zap does not seem to stop the rotation of a molecule that has been
zapped.
Here's what I do and see:
My app load a large molecule (several seconds to load) with _script. At the
end of my script I change the molecule's orientation.
zap; load <large molecule>; rotate <to a new position>;
After the large molecule loads and is still rotating, I change my mind and
decide to have my app load a small molecule. At the end of this second script
I change the smaller molecule's orientation.
zap: load <small molecule>; rotate <to a new position>;
Here's what I see:
The small molecule replaces the large molecule, but jumps around as it
is rotating when using _script. Something that doesn't happen when I use
_scriptWait.
I see the msg, "Jmol script terminated", in the script callback before
the large molecule completes its rotation.
Question:
Should I be using an additional script command to stop the rotation
before zap when I load another molecule?
Should I be waiting for some callback to tell me that the rotation is
complete?
Thanks,
