For both 4.6 & 5.0 on the mac, saving a project generates the following
error: "NotImplemented: ClassBinding or a superclass should implement
objectForDataStream."
The comments in the method suggest this shouldn't have been released to a
stable version: "It's not yet clear how serialization should work in the
presence of environments".
Problem 2 is that if I then "abandon" the error messge, the workspace is
then flooded with "MessageNotUnderstood" error boxes.
Is "environments" something experimental that should be switched off?
Best,
