Re: [idvusers] Error generating graphic from command line

We found the solution to our problem.

We simply uninstalled the 64-bit version and installed the 32-bit version
which gives you the install option of selecting Java3D version 1.3 instead
of the default 1.5. I saw this as a troubleshooting solution in a thread
several years ago.  That did the trick on our Linux system.  So, if anyone
ever repeats this problem trying to create graphics from an ISL file off
the command line, try using 32-bit version.

Thanks for all the help,
Mike U
