and of course you are both correct , I have a circular reference, basically an object A referencing�� object�� B�� which references object A. No wonder why is not gc. Thanks for helping me out spotting this.

If there is no Object that reference your object you can force a Garbage
collect with "Smalltalk garbageCollect". If your object is still here
you can try to see what point to it with "(X allInstances collectAsSet:
#pointersTo) inspect".

When the reference is spotted you can try to remove it then garbage
collect again.
