[Moose-dev] issue deleting a moose model

Hi, yesterday I tried to delete a moose model from my image using the function Utilities>>Delete on the moose panel. The model disappear from the list but saving the image it has the same size. Executing "MooseModel allInstances" I saw that the model was still there. I tried to close all windows and then i execute "Smalltalk garbageCollect" and again the saved image has the same size because the model has not been removed. I'm working on the pharo dev image 10508, Moose-Core 215 but i detect the same error in an older image: pharo dev image 10502, Moose-Core 208. Cheers, Fabrizio
