when I saw Itamar's emails (copied below) I checked on my box. Same results here on a NT 4 box with Zope 2.1.0b.

I moved the PythonMethod product folder from my Zope 2.1.0b folder to my older Zope 2.0.1 folder. This cured the new version and moved the problem to the older version.

Sorry this took so long, but it was a really subtle stupid bug on my part. You can download 0.1.6, or simply add '.copy()' to the end of line 6 of Guarded.py from version 0.1.5 Sorry, Evan @ 4-am
