I figured something changed in the heart of the language, because all
other components were unchanged. I am not doing anything fancy with
it, just drawing county lines (as an example... I also draw roads from
another shapefile) on an existing map projection. The routine does
end up doing what it's supposed to, but it takes unreasonably long --
several minutes instead of a blink. Here is what I'm using (and have
successfully used for years):
drawstates,'COUNTIES.SHP',attribute_name='NAME',statenames=' ALL'

Thanks in advance for looking into it!
Brian
