Hi Andreas,

this function was copied over from another class, where it worked, 
having had a deeper look now, the difference boils down to either
trying to

- save a  Dictionary        (works), or trying to
- save an OrderedCollection (doesn't work)

I don't understand enough of smalltalk to see where contexts fit into 
the picture.

I want to save some application data to transfer it to a new image, 
maybe I should try imageSegments?


Thanks a lot,

Ingo
