Comment (by glynn):

 Replying to [comment:19 hamish]:
 > With the latest nightly WinGrass 6.4.0svn build (r40876), I get this
 error message if 'nviz --ui' is called from the msys command line,
 elev=elevation.dem at PERM, and the '-v' verbose flag is ticked (one -, not
 two).

 > the popup window error is:
 {{{
 unknown or ambiguous visual name "elevation=elevation at PERMANENT":
 }}}

 Tk uses -v itself (it's an abbreviation for -visual). This specific issue
 can be worked around by using "--" in the nviz script, i.e.
 {{{
 -exec "$GISBASE/etc/nviz2.2/nviz" -f
 "$GISBASE/etc/nviz2.2/scripts/nviz2.2_script" ${1+"$@"}
 +exec "$GISBASE/etc/nviz2.2/nviz" -f
 "$GISBASE/etc/nviz2.2/scripts/nviz2.2_script" -- ${1+"$@"}
 }}}

 But I'm more inclined to suggest back-porting r40879. I think that's bound
 to be the most robust solution.
