Kevin,
I've been in touch with Steve Chiswell on this matter. He told to
update a file (g2varswmo2.tbl) in $GEMTBL/grid, which I did, but I must
have edited the file incorrectly. So, I asked him to post an updated
file. If he doesn't email a notice to you or Gembud, I'll send you the
file I get it.
