If you put that command at the end of Jmol.js, it will work in all your
tutorials -- they use the same Jmol.js, right?

Certainly suggest it. I can't think of why not to do this. Maybe if your
scripts use the Jmol "javascript" command, there could be a problem, but
even then it might  be fine. This is automatically set TRUE for the signed
applet, and it works great, so I suspect it is fine for the unsigned as well
-- just didn't want to make that the default for the unsigned applet when I
set up the signed applet. But the signed applet is so successful now, maybe
we should consider doing that for the unsigned as well. I have to think
about that...
