Last time I chased obsolete classes and I found a nebraska category in PasteUpMorph. Now I did a search over all classes if there are more nebraska categories. And there were a lot. Most of them were empty. Even the category I removed myself. Is it true that Monticello isn't able to delete method categories? I attach a changeset that removes the method categories because with a changeset it works. Or did I something wrong? After removing the empty ones there are still two left. 1.) Canvas->Nebraska/embeddedWorlds containing a method transform2By: clippingTo: during: smoothing: A flag is indicating that this is added to Canvas for nebraska to work. The right method seems to be transform2By: clippingTo: during: smoothing: (no 2 after transform) However this method is referenced from to places: BOBTransformationMorph>>drawSubmorphsOnREAL: and TransformationB2Morph>>drawSubmorphsOn: Is anybody familiar with those morphs. It appears that the method can be substituted by the original method but I'm not sure. 2.) SketchEditorMorph->Nebraska support All those methods don't seem to be rippable from the class as they are interwoven with all other methods. Maybe a re- categorization will do. Any ideas? Norbert
