I assume that you are referring to the JmolAppletControl buttons on the
http://www.jmol.org/demo pages

These buttons are done as JmolAppletControls to make them more portable to
run on other systems, esp Mac OSX. But this was done in the days before
LiveConnect was working ...

The JmolAppletControls themselves are quite simple. But the browser has to
allocate an AppletContext for each one, and that is probably a set of
complicated data structures.

But, I do not mean to be defending the JmolAppletControl buttons ... I
hate them.

They were done because there was no other solution on Mac OSX. And because
they were intended to be compatible with the Chime plug-in buttons. So the
chime2jmol.pl script generates them when it sees chime buttons. But I am
not very happy with chime2jmol.pl these days ... it hasn't gotten much
attention and I am not sure whether or not it is practical to expect
automated conversion of chime html pages.

I don't know if it is possible, but I would rather eliminate the
JmolAppletControl buttons completely.

I do not think that we should use hidden frames and immediate buttons for
help system pages that are designed to show functionality. Hidden frames +
immediate buttons add a lot of complexity to a simple page.

Since LiveConnect now works on OSX, It seems to me that we should use
straight HTML buttons. I think that is the simplest mechanism and should
be the recommended way to create button controls.
