Default disable content copying in a pdf

No - and even in Acrobat which has that option, it will only stop
copying for about 10 minutes. If someone can see the document they can
copy it.


Not necessarily so Graham.

It's dependent upon what encryption method is used (40-bit or 128-bit).
Also upon what security options are set and the number of pages (there are
some tools that will de-crpypt a 1-3 page 128-bit encrypted however these
tools choke on more pages.

BTW, the encryption additions require the full-version of Adobe and not
the free reader.
Even PDF's that have encryption set MINUS-a-password cannot be de-crypted
in the free reader.
