I'm new to Zope and reading "The Zope Book". Following along with the book, I created a version for making changes and not go live with them until all changes were complete. The problem is unless I am working in the changes version I get the following error when accessing some, but not all, of the help topics: Error Type: VersionLockError Error Value: ('"\\x00\\x00\\x00\\x00\\x00\\x00\\x00\\xec"','/myChanges') Error does not occur in any of the help topics if I am working in myChanges version. I'm using Zope 2.6.1 on Windows 2000. Any assistance would be appreciated.
