Wouldn't that be nice. I don't know, and I don't know how to find out. What
it does is distinguish between the thread that started the applet and the
thread that executes in response to a user action such as clicking a button.
"UseCommandThread" transfers all commands that do not include the Jmol
"javascript" command to the thread that started the applet.
The fact that the signed applet (which uses this by default) has worked
flawlessly for so long suggests that this works.
Paul, could you try a couple of additional tests?
In each case, from both the Jmol console and from a user clicking a button
on a page, with and without "useCommandThread":
load "somefile"
load "somefile"; javascript "alert('done')"
load "somefile";/*SPLIT*/;javascript "alert('done')"
load "somefile"; #javascript
See if they all work, or only some of these work. Because the different
threads have different requirements, and these special words influence
which thread is being used when using a command thread.
