[GRASS-dev] Mac xterm wrapper problem with wxgrass

[Agustin Diez Castillo]

I have observed similar behavior on macintel. Mainly, after an update.
If both X11 and terminal are opened grass.sh launches terminal and
nothing happens, quiting X11 sometimes fixes it and others I need to
quit terminal as well but I would swear that this happens also with
tcltk. I will keep an eye on it.
