While working through the tutorial and introductory exercises, I appear to have pointed myself into a corner. I worked some versioning examples and thought I had closed the version. I resumed my study and eventually returned to Zope to try adding a new object in the root folder. This resulted in a VersionLockError message and stack dump. I think I've figured out that this is a rather dramatic way of saying "this folder is locked by another version". I'm not sure how the root folder ended up locked, but it does show that icon. I then tried to undo my way out of the problem. This undid the creation of the version object, but not the objects locked by it. Now I can't get into the version, because the version does not exist. I tried creating a new version object by the same name and was able to do so but it did not end up being associated with the locked folder. It would be easy to simply uninstall Zope and reinstall it. I have nothing invested in the current configuration. But I am uneasy about the possibility of this happening later when I do have a site built and in production. I also suspect I will not be the last one bit by this problem.
