[lug] Gnome Menu Editor problem

Hi.

I am a newbie running Ubuntu with what is no doubt a trivial problem.

I have installed a game called Glest into /usr/local/games/glest. In
this directory there is a shell script called glest, which when
executed (by clicking on it in nautilus) runs the game. I can also run
the game by typing /usr/local/games/glest/glest at the command line.

The problem I have is I am trying to add a shortcut in the Gnome menu
using the Applications Menu Editor. Using the command glest does not
work and neither does /usr/local/games/glest/glest. What am I doing
wrong?

Any help much appreciated.
