Hi Downloading the latest OB today with: Gofer new squeaksource: 'rb'; package: 'AST-Core'; package: 'Refactoring-Core'; package: 'Refactoring-Changes'; package: 'Refactoring-Critics'; package: 'Refactoring-Environment'; load. Gofer new renggli: 'omnibrowser'; package: 'OmniBrowser'; package: 'OB-Standard'; package: 'OB-Morphic'; package: 'OB-Refactory'; load. Then I change the superclass of the template of an existing class, then accept: Object subclass: #FileContentsBrowser instanceVariableNames: 'packages infoString' classVariableNames: '' poolDictionaries: '' category: 'Tools-File Contents Browser' The superclass is not changed, instead OB changes its focus to the superclass. Can anyone confirm this bug? -- Simon
