[GRASS-dev] nviz won't launch from wx GUI menu in WinGRASS

I took a look at the way that NVIZ is launched from the wx GUI menu. The menu item calls a script called "nviz" that lives in the $GISDBASE/bin folder.

The script launches nviz. The menu item does indeed call the script and the script launches. But the code in the script doesn't correctly launch the NVIZ module in Windows.

Here is the code. Perhaps someone can ID what is wrong with it.

if [ $# -eq 0 ] ; then
   ##nviz is opened in GUI
   exec "$GISBASE/etc/nviz2.2/nviz" -f "$GISBASE/etc/nviz2.2/scripts/nviz2.2_script"
   exit 0
fi

exec "$GISBASE/etc/nviz2.2/nviz" -f "$GISBASE/etc/nviz2.2/scripts/nviz2.2_script" ${1+"$@"}

The weird thing is that this DOES seem to work if you launch it from the Msys GRASS terminal in Windows.

I can just confirm that nviz reliably works from the MSYS GRASS terminal in MSWindows - we have used
it a lot by now, when run from wxGUI it launches it but the TclTk interface does not open

from the Cmd> prompt in the wx layer manager it fails.

Probably for the same reason that the code in the nviz script fails--whatever that is.
