OK, Jonathan. I think I found the problem. Please try what I just checked
in -- do a build, and then use jmolData.jar instead of jmol.jar.
Formerly:
JmolData.jar -s foo.spt
execute the script foo.spt with absolutely no graphics and no rendering,
including no image creation
now:
JmolData.jar -s foo.spt
execute the script foo.spt still with rending for image creation, just
not for screen display
Jmoldata.jar -n -s foo.spt
as before, now for performance enhancement, no graphics of any kind.
Let's see how that works.
