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 :-)
