Follow-up Comment #1:

Confirmed.  It was probably this changeset from jwe to have better Matlab
compatibility:

summary:     error for functions called with too many inputs or outputs


The issue is the graphics callback functions defined as subfunctions in
__add_default_menu__.m.  The function prototype is


function grid_cb (h)


but all graphics callbacks are invoked by the interpreter as


callback (graphic_handle, event_structure)


Changing the function prototype to


function grid_cb (h, ~)


restores functionality.

Except for a few graphics callbacks, the event_structure input is unused and
unfilled.  I think going through the code and verifying the callbacks all have
'~' as the second argument will fix this.
