tk_octave xauth and examples

[jfl]

Below is a copy of the error message.  The third.m file is a variation
of the tk_octave Tk_me simple start/stop counter example.  It works 
fine when logged onto the machine cuba.  It doesn't work when I rlogin 
or SSH2 into cuba.  Note that the command sombrero(100) does work fine 
whether on console or remote so the problem seems to be in tk_octave.
Probably a config problem but other than setting DISPLAY and xhost +, I
don't know what to do.

I searched in the help for tk_octave and X or X11 or xauth and nothing
was found.

Separate issue, the Tk_me screenshot of the sombrero+menu is nice but the 
examples and demos I have don't put it all together.  Does anybody 
have a complete example or was that left as an exercise to the student?
