Hi Bill,

Unfortunately, when I re-compiled the package with your new
DisplayImpl.java, there are no null pointer exceptions, but I still have
the java.lang.InternalError's that I had before. When I try to run the
spreadsheet with 12 columns and 4 rows, I still only see mappings in the
first 12 cells and the rest are just plain black squares with not even
the white outline of a cube that blank mappings would at least show.

This same error shows up when I run the program at my old computer which
can run a 4x4 SS just fine. Problems occur on that computer when I try
to use a 12x4 SS.

Let me know if you need my files,
Thanks,
Michelle

Hi Michelle,

Thanks for the information. This problem is hopefully fixed by:

  ftp://ftp.ssec.wisc.edu/pub/visad-2.0/untested/DisplayImpl.java

Please let me know whether this fixes the problem.

Cheers,
Bill
