Hi Marcus, I guess you are aware of this. I looked at Undeclared in the reloaded Core and I found out that one method that makes it is different in the latest Pharo 1.4 and belongs to newer version of the package (Settings-System v.17). This version is not present in the Pharo repository but what is more interesting - it is not present also in the Pharo14 repository. Cheers, -- Pavel
