“Simple inspect” works fine. THe trace is:

If it isn’t obvious what is going wrong from the above, I gues the thing to do is reinstall Pharo, and go through the steps of installing the various packages while recording them. If I get the same error, I’ll post the video of what I did on youtube. If I don’t an error, then it was operator error from the start, obviously. Thanks for your help.
