Hi fokls: Let's do the last effort. We have little failing tests in new Dev image. We even have all the OB tests in green!! thanks Lukas Now, the current failing tests are: - ProcessSpecificTest has two tests: testDynamicVariable and testLocalVariable both fails when the first time that are run. However, if I re run them, they are green. The same happens with MCPackageTest >> testUnload - testUndeclare Here I have a problem with OB for example. OBPluggableService is used in OBDefinitionPanelTest >> scanCommands: but OBPluggableService doesn't exist. I don't know where it is that class. - OBButtonBarTest >> testLayout is failing in "self assert: rects third right <= bar right" because "rects third right" answers 402 and "bar right " ansers 400. - There is also ObjectFinalizerTests testFinalizationOfEquals As it is says here: http://code.google.com/p/pharo/issues/detail?id=1564 Ok, any help you can give would be cool. Thanks Mariano
