I have run into a problem in upgrading our production servers to Jmol
11.9.8 (from 11.5.37). We have a number of cases where one machine,
let us call it journals.chester.iucr.org, hosts framesets in which a
frame contains a Jmol figure. Sometimes the component frames are
served from the same server; sometimes they are served by a different
one (scripts.iucr.org). With the upgrade, the latter case fails with a
Java General Exception (JmolApplet class not found).

An example of what I mean is given at
   http://journals.chester.iucr.org/test.html

The difference in behaviour can be traced to the fact that Jmol.js
implements some code to locate the applet. In recent Jmol.js, that is
done through calls to top.location.search.indexOf(), where previously
document.location.search.indexOf() was used.

If I change "top" back to "document" in Jmol.js, I can recover my
desired behaviour. Can this change be implemented in future versions
of Jmol.js, or is there a good reason why it was changed?

Thanks
Brian
