Thanks for looking into this. I'm actually using 6.3, updated the cvs today.

Eric,

I'm completely baffled. It must be some other kinds of changes in GRASS
affecting this. Is the only one that doesn't work? You can grep
run_panel
*.tcl in the /etc/gm folder and see what else uses it. You can make a
change
with a text editor with no need to recompile.

I have to make a confession that the version I'm working with is a
couple
weeks old, but has all current tcltk files. I'm concerned that some
other
change in the tcltk parser is creating problems with running some
things.
i.group should not be problematic since it doesn't require an xterm to
run.

The "run" procedure is used widely. I can think of no reason why "exec
--
i.group >& /dev/null" should not work. I notice that you do not have the
new
devnull variable that makes this workable in Windows, so you must be
running
6.1 or 6.2. I don't know whether that makes a difference or not.

Given all this, I'm forwarding this to the general developer list to see
what's going on.

Michael
