So , if I understand you, Because I ran the original code using the
Pythonwin environment, I produced the objects in module __main__ NOT in the
module I though they were being created in ( in my case a module called
octavia which contains the class Programmes).

When I then ran with my test module, which imported octavia, The Unpickle
process believed it was trying to unpickle objects defined in __main__ NOT
from within octavia ?

So should I then have a module 'above' my octavia module which will import
octavia for it to work?
