The bug I'm describing is VERY annoying and very real. I managed to get a
20M snapshot of a Data.fs that exhibits the bug. I thought that the Zope
team would be interested... ;-) Anyway, since some operations done in the
interface brings functionality back it is something at least partially Zope.
The only major problem is that it is not predictable! You can sometimes do
tens of open/save from HomeSite and nothing goes wrong! 

I've dumped some of the traffic towards the machines but I didn't had time
to analyze it. It looks like IE's requests leave the XP workstation arrive
at the Zope server but the Zope remains silent... :-|
