This really is a problem. Tim, we should have one EVEN SIMPLER that does not have messagecallback or pickcallback in the applet code.
just the absolute minimum:
<param name="progressbar" value="true">
<param name="script" value="load 1crn.pdb;color cornflowerblue;">

I have tried Tim's new page. Works beautifully, AS LONG AS the applet has not been previously loaded from another site. If I access another page and then try Tim's, no action. If I load his first in a fresh safari, it runs nicely -- with all buttons. But then the next page will not -- no matter where it is -- mine, Bob's.... this is true it I am using tabs for the different pages, or if I try to load sequentially into the same tab.

OK, Phil. You are using Mac/Safari, right?
Looks like we have the start of a good mystery. Please tell us your page so that others can check. We need a good, reproducible test.
Q1: Could this be a jmol version problem? My pages (given below) are both using the applet version: [Jmol Version 10.00 2004/12/17 18:55]
Q2: Why me? Can this be shown for two sites NOT involving my pages? Who else can point us to sites using messagecallback handling?
hi,
I've posted a very simple test for accessing the JmolApplet. it does away with almost all complexity that can cloud this issue. you can see it here:
<http://dev.molvisions.com/debugging/jmolcalls.html>
it includes three methods:
1. getElementById 2. document.appletname 3. document.applets[]
so far, all three methods work for me in OSX: Safari 1.3, FF 1, Moz 1.7.3; also in IE6 (winXP).
a few oddities:
1. the messagecallback is somewhat inconsistent in its output. that may have to do with the way I implemented it. it does not seem to adversely affect the command stream, though.
2. I developed this on my localhost server, and it worked without flaw. then I copied it to my LAN www server and, without quitting my browser, tried it out. it failed with all sorts of security exceptions. I cleared my browser cache, quit and restarted, and now it works fine.
oddity 2 may point to the issue of accessing different Jmol pages, IOW different JmolApplets, and somehow confusing the browser or the JVM. but it does not point to a problem with actually sending scripts to the JmolApplet. we should spawn a new thread for discussing the cross-page problems, IMO.
one final note: method 2 above:
document.appletname
must account for the DOM of the page. IOW, if I put my applet inside a form named myform, for example, instead of directly under the body tag, my call would have to change to
document.myform.appletname
the other two methods do not require this change.
