[Pharo-dev] Memory leaks with Spec?

Hi guys this is strange I cannot get rid of Spec based ui instances. I tried many LoggerUI allInstances do: [ :each | SystemAnnouncer uniqueInstance unsubscribe: each ] LoggerUI allInstances do: #delete. Smalltalk garbageCollect Nothing changes. Each time I create and close it does not get garbage collected. I remove all the announcement registration from my code but nothing changes. Stef
