Not sure what's going on.
Jmol.js in inserting an applet tag (Jmol #1) for Chrome and fails to display, but when that code is written directly (Jmol #2) it works.

I've read about changes in the way recent Chrome deals with object tags, but not with applet tags. And since Chrome/Win hasn't got this problem, I think that's not the issue now.

Anyway, I'm trying to direct Jmol.js to insert object tag for Chrome and Safari instead of applet tag, let's see if that workaround solves the issue.

Can you please test this new version
particularly under Chrome/Mac and Safari?
