Following my research in SqueakLight, a bare morphic system, I found:

In Project class newMorphic

"ProjectView open: Project newMorphic"

In ProjectLoading class openName: aFileName stream: preStream fromDirectory:
aDirectoryOrNil withProjectView: existingView


ProjectView openAndEnter: proj.

ProjectView is not in actual 3.6a , but I found in SqueakV3.sources

Actual SqueakLight is 7.5 mb, stable and Undeclared inspects are empty.
Still I'm wish to learn how to chase cases as this, class in some code not
longer in image.
Any ideas ?

Very thanks for support.
