[Zope] some zope page content missing

[Sean Kelley]

I have seen and heard of some people coming to my site and not seeing 
pages or seeing only partial pages.  Is there a known IE bug out there 
that would cause this or is this possibly a known zope issue.  most of 
my pages are straight html in dtml document and dtml methods and I am 
running Zope 2.6.1.  

This page apparently is not showing for some people:

Also, there is a graphic above all of my ads on the right hand column of 
this page above the google ads and I have seen on someone's IE6 browser 
that not all things show up.  There are 4 graphics in this right column 
if you cannot see them all.
