Hi, yes! Thanks for the help, searching it seems that I have shortcuts that has references to obsoletes instances, I will see how to remove them.

How can you have an instance of a class X if the class X doesn't "exist" anymore? �The whole point here is that an object's class is also a strong reference to the class, and generally it's skipped by object reference finders. �The way you find those is by sending allInstances (or equivalent) to the class.

"Smalltalk fixObsoleteReferences" didn't completely work for me when i
had that problem, i had to find out where those references were.
I think looking for strong pointers of the ObsoleteClass would be a good
start.
