Many thanks for the answers (I will give some comments in a separate mail).

I do not exactly know what "kind of answer" you expect....but lets see ;-)

I did the installation of self in the "ordinary way" (having the binary 
accessible in /usr/bin). I start a snapshot via "self -s MySnaphot.snap".

2 things that seem to be somehow strange:

1.
I used self first with a live-version of ubuntu 9.3. There, the refresh 
(or redraw) of the world-object did not work right: whenever I opened 
the Demo snapshot and scrolled right in the world object, "a chaotic 
collection of pixels was shown". Just taking one window into the hand 
and "wipe over the world" corrected it. Now, I am using a regular 
installation of Ubuntu 9.10 and this effect is no longer there. I do not 
know whether this effect depends on the live version or on ubuntu 9.3.

2.
Whenever I saved a snapshop and reopen it in the way as described above, 
I always get the following message:

##############################################################
VM version: 4.1.13

Adjusting VM for better UI2 performance:
   _MaxPICSize: 25
"Self 1"   _Flush
Could not open display "ROSE:0.0", error: primitiveFailedError
     1. Try Again
     2. Try Local Display
     3. Give Up
##############################################################

(rose is the name of my machine)

3.
Leaving self from the terminal is slightly "unwieldy": I have to press 
CTRL-C for some times, say that I really want to leave Self, etc.


By the way.....since we are near christmas....
It would be great to have windows version of self (I know, much 
work...someone has to do it), since it would be easier to convince some 
of my students to "play a little bit with self".

....just a comment....since it is almost christmas ;-)
