I am on Poser 8.I havn't deleted P7 yet to be on the save side.Until now I havn't used P7 again,because P8 became closer to that what I want  Poser to be.New UI ,full body morph brush and dependend parameters are the features I never want to miss.After solving some start up problems with the librarie manager ,P8 runs like a charm.Well : Poser 8 rules - forget all previous.
