There is a strange problem with estron.cml in the applet.
The rendering behavior is different, depending upon the version of the
JVM. (My swag is that exceptions are getting thrown at different places on
the different JVMs)
Even JVM 1.4.1 of the appletviewer does not render it properly (all atoms
are white, no bonds, as though none of the atoms are configured properly)
Other molecular models seem to work fine.
In the app, on the other hand, everything looks OK.
