This works for me (and always had). Which fltk version do you use? I
have 1.3.2-5 in debian jessie.

I hesitate to do this immediately because this may shadow the real
problem. If you add

 endfunction

 function grid_cb (h, e)
+disp("this is grid_cb"); fflush(stdout);
   hax = __get_axes__ (h);

Do you see the msg when clicking on Menu->Toggle grid on all axes?
And if the grid doesn't appear, can you move the window outside the
screen and back (this causes a fltk redraw).

I hope you understand that I just want to grasp the cause for this
problem and to my understanding the event propagation after grid_cb
should be:

grid.m:  set (hax, "xgrid", "on", "ygrid", "on", "zgrid", "on",
graphics.h: void set_xgrid (const octave_value& val): mark_modified ();

which should do the toolkit notification and then trigger the redraw.

What distribution are you using? Perhaps I can install it in a VM and
see there what's happen.
