[Zope] PDF files in Zope 2.6

[Jason Bush]

We recently upgraded from Zope 2.5 to 2.6 and are experiencing a problem 
with PDF's
loading via the browser (any) plugin. The Adobe plugin loads in the 
browser and the
user is presented a blank screen, as the content is either not sent or 
received properly.
This problem does not occur with all PDF files, however the ones that 
are being
affected did work with the prior version of Zope. Does anybody have 
knowledge of
the cause of this problem or where/if a fix can be obtained.

Also if the pdf's in question are downloaded rather than sent to the 
browser, the content
comes accross fine.

TIA,
Jason
