movie.pdb issues resolved, sort of

Miguel, maybe you can tell me what I observed earlier today but couldn't reproduce. At some point testing things, I got the strangest callback messages from Jmol. Whole function pointers were being returned. So, for example, I saw something like

  getter function {   [native code] }

or, oh, I can't remember. Really surprised me.

Sorry if that's too vague. I guess the real question is whether you've seen anything like this.

That is, instead of issuing the .script() command directly, if the
JavaScript
starts a new thread with a 1 millisecond delay that executes the script,
then all is well.
What a disaster.
I will start an off-list email thread with Steven Michaud, author of the
Mac OS X javaplugin. He (obviously) has quite a bit of experience with the
LiveConnect implementation on the Mozilla browsers, so he may be able to
shed some light on it.
If possible, we should figure out what is happening and
fix it from within Jmol.
I think that we need to eliminate the callbacks. I realize that I have
been preaching that for a long time ... and have yet to come up with an
alternate  implementation.
Was there a change in the way Jmol returns values with
the script() command? I know I was suggesting a change there.
I do not recall making any changes. The script command has always returned
"void".
But the way that the 'callback' functions work could easily have changed.
Starting new threads with setTimeout() can really be a headache.
Clearly.
