Andy,

Everything works for me ... except that selecting [Edit->Grid] from the menu (i.e. no effect).  However if the axes is active, then typing "g" does toggle the grid, as does the "G" button at the bottom of the figure.

Ben, Andreas,

I remarked on this before as well.  You can get it to work by causing the event loop to run.  For example, if you return to the command window and hit <RETURN> the grid will appear.  We need to use the same solution that was used for the 'g'.  In this case, I just added a drawnow () command at the end of the grid_cb function in __add_default_menu__ and it works correctly.
