Hi Trygve,

Did you see my earlier reply suggesting that you use the VM at
http://www.squeakvm.org/~lewis/MacOS-test-Javier/ ? I believe that I sent
it directly to your personal email address, but I don't know if you
received it.

The newer Cog VMs used in Squeak all-in-one and Pharo will not work with a
Squeak 3.10 image, but any of the traditional context interpreter VMs
(including this recently built VM provided by Javier Diaz-Reinoso) should
be fine.

A bit off topic from your orginal question, but I would also encourage you
to take a look at http://try.squeak.org/ as a source of inspiration. This
is Bert Freudenberg's remarkable SqueakJS running in a web browser, and it
might prove quite suitable for certain kinds of software demos where you
want a run-anywhere capability.

You should be able to drag and drop your BabyIDE image onto that web page,
and run it directly in your your web browser with no need to install a VM
at all.
