Obsolete classes - I can find pointers to them, but how to get rid of them

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
:-)

Sophie

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 :-))

Ramon Leon posted a useful utility that attempts to clean up a variety
of common problems in an image:

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

this comes with extensive disclaimers

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

Edgar
