Hi Alain. DEVImageCreator has to be updated to use the new preferences. I can do it but it will require much more than for me than for you ;) For preferences it is DEVImageCreator >> setDefaultPreferences it is using Preferences class for the moment. It should be updated to use Settings, isn't it ? BTW, Preferences is still present in Pharo 1.1 and thus, setDefaultPreferences is still working but I guess it should be updated. Do you know when Preferences class will be completely removed? Pharo 1.2? Thanks! Mariano
