I think there hasn't been a reprint of the Zope Book (as from zope.org), 
even though the newer versions are much enhanced.

Well, that's a different story, and I think I can explain it. DTML 
documents are stored as objects in Zope, as you can probably tell from 
the way they're used, and once created don't refer back to their on-disk 
sources. So you must destroy and recreate such a thing in order to see 
any changes. If a DTML object is stored as an attribute of the class, 
DTML objects with the behaviour of the filesystem code at the time of 
instantiation will persist in that instance. I suspect you're doing 
this. Create them instead as attributes of the module, which is 
destroyed on Zope shutdown and re-run on startup (or refresh).

Or it could be your browser cache.
