Hello, I tried to download Hapao in Pharo 1.2.2 with the code in the Hapao website : Gofer new squeaksource: 'Spy'; package: 'ConfigurationOfSpy'; load. (Smalltalk at: #ConfigurationOfSpy) perform: #loadDefault When I load the packages, there is a dependency with SubscriptionRegistry package, what is this package ? Finally, when I want to run Hapao in the Pharo menu, there is the following message: MessageNotUnderstood: PluggableDialogWindow>>beResizeable. In fact this message does not exist in the system, is it because of SubscriptionRegistry package isn't load ? Or because I did something wrong ? Thanks for answers. Romain
