[Etoys] Opening .pr error

[Yoshiki Ohshima]

  Tibi,

  Etoys which is being developed gets some new features and new kind
of objects now and then.  That certainly happens (many times) since
build 406 and build 500 something.  Usually, a project can be carried
over to a newer version from an older version, but the opposite
direction is not guaranteed at all.

  I would like to take a look at your project and what new object is
getting in your way.  There is a case by case solution for this
problem.  I really don't see real benefit to provide complete solution
for migrating a project from newer version to an older, but I may be
able to help in some cases.

  If your colleague has B2, I was told that "Etoys-41.xo" should work
on B2 with 406.  You can just update the Etoys activity and hopefully
your project would load into it.
