Hi Kevin,

Please try the proposed fix at:

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

Note this is incorporated in the visad.jar and visad_src-2.0.jar
files at ftp://ftp.ssec.wisc.edu/pub/visad-2.0/untested/.

If this doesn't fix it, then please send me the test program.

Cheers,
Bill
