PointerFinder reveals numerous pointers to obsolete classes. All of them seem to originate from something that appears (in the PointerFinder window) as either: #Refactoring -> Refactoring class or #EventManager -> EventManager class with lots of additional info.
I have no idea how to even reach the handles that are holding onto these obsolete classes, them seem to be from Squeak code. Any pointers appreciated :-)

you can search the swiki for "cleaning up junk". Also I seem to remember this topic was discussed on squeak dev in the past. I don't feel this is a beginners topic :-))

If this doesn't help, at least you know that it's not a simple problem!

This is some code from MC1.5 which I think is the most comprehensive attempt to rehome obsolete instances.
this comes with extensive disclaimers

Keith, made a Mantis report with this and could go into 3.10. Also any related to image cleanup.
