Hi Bernat, yes, I ran Smalltalk fixObsoleteReferences. And also ran the garbage collector but if find the obsolete references I get the classes anyway.

Yes, in someway seems to be an instance of this class... but how can I find them?

Hi Gisela,

Have you tried DoingIt:�Smalltalk fixObsoleteReferences?

Hi, I'm trying to fix this, I have Obsolete classes in the system and I want to remove them, as long as I understood this is because this classes are gone and in some point someone is referencing them.

I do an extended search an get nothing, but still the obsolete classes are there... I don't find no one with references to it but if I run:
SystemNavigation new obsoleteClasses�select: [ :each | each isAnonymous not ]�

I get the problem classes.

I found this thread about a similar issue but don't know how to solve the problem�http://lists.gforge.inria.fr/pipermail/pharo-project/2011-January/038824.html

Maybe someone could help me...
