Hi Mike,

Here's another approach we have just started playing with here:
We're running Hummingbird's Exceed X emulator on a 486 microcomputer
(under MS Windows), running GRASS remotely.  It's a little 
shaky, i.e., if you drop ;another window on top of your 
GRASS monitor window, you've lost whatever was painted 
there.  But you can easily  cut the image out of the 
monitor window and paste it into the graphics package of your choice
(MS Powerpoint or Lotus Freelance).  It''s easier doing 
miscellaneous annotations with these rather than with GRASS's 
d.title, d.label, etc., and then generating your slides.  I don't
know what Exceed costs, but we got it cheap through some University-
wide licensing scheme.
