fixed in CVS.
- allow nan elevations to contribute to the cum. dist.
- if a nan is encountered plot what we have so far & reset line array
- if a single point is found between two nans, draw a dot. (oval with
  radius 0 was the best way I could figure to do that)

I wonder if there is a way to only run r.profile once?

It applied to the profile ending over any null area.
e.g. if you drew a profile over "fields", if arrow ends over a null area
the rest of the plot was incorrectly stretched to the right bound of the
axes box. Now it should draw where it was supposed to, and raise/drop
the pen as needed.

thanks.

Is the font as huge for you as it is for me? -size 10,11,12 better?
(perhaps it's my config; same for bolddefault "Map Layers for Display 1"
and introfont text)
