Hello, We just added Stephan and Torsten to Artefact contributors so they should be able to commit. Therefore we don't find the account of Gary Chambers on Smalltalk Hub. Do you have one?

Ok, new try to understand: I loaded Phratch in a new image, with the last vm, it works fine. Then I took the structure of the one-click and replace the contents by the working vm, the working images and all my plugins that works outside the one-click package.

Re: [Pharo-dev] taking a custom screenshot of a submorph

One could, but it is not the same. The inspector offers a quick visual interface that allows you to browse a complex morph hierarchy. Taking the screenshot is secondary, but when combined with the visual feedback it gets more interesting.
