That sounds very suspicious - what are your IE cache settings?

This bug report was related to the fact that the user was 
accessing the file through a Squid cache and that at the 
time (Zope 2.0.1) there was a legitimate bug in the way 
that "If-Modified-Since" headers were handled. Squid was 
actually returning the file to him. It should have been 
marked completed quite a while ago (I just did that).

I am using IE 5 (5.00.2314.1003), cache settings set to: 

"Check for newer versions of stored pages:
  x Every visit to the page

...and I cannot reproduce the problem that you are 
describing :( Are these your cache settings? Are you 
accessing the server through any kind of proxy?
