Roger,

  I just forwarded Bill's message to the GRASS-5 list.

  Me, neither. I wrote to them and explained that it wouldn't work with
Navigator-4.77, mozilla-0.9.1 or opera-5.0 (identifying itself as MSIE5.0).
Still broken.

  Read the article. They _did_ change the data and they modified SDTS
format. Strangely enough, only ARC/GIS-8 supports that format. And the GS is
a complete ESRI shop (which is how ESRI got to be as big as they are).

  Politics hits the GIS world, too. Welcome to my world. :-)
