hmm.. i trying to install polymorph-widgets from universes on 10156- dev image

Did you try to patch the PCPackageLoader>>basicLoad method to disable the progress bar before loading as described in http://wiki.squeak.org/squeak/6005? It's also best just to have only one window (workspace) open, since some UI changes dont work with existing windows. Otherwise use the new script loader script from the inbox. In a 10160-dev this works without problems. Torsten -- Sensationsangebot nur bis 30.11: GMX FreeDSL - Telefonanschluss + DSL für nur 16,37 Euro/mtl.!* http://dsl.gmx.de/?ac=OM.AD.PD003K11308T4569a
