Lockergnomie Caleb Ciampaglia has documented a document dilemma:
“After upgrading to the latest and greatest Adobe Acrobat Reader
(5.05), I encountered an error message when I was using a Web
based reporting tool at work. Whenever I tried to view a report
(which was a PDF file), I received an error message: 'linear data'
error. After a little research on Adobe's Web site, I disabled an
option called 'Allow Fast Web View' and everything worked
wonderfully, though it was a tad slower. This option can be found
in Edit | Preferences | Options. Apparently, it is a new method
that Adobe uses to transfer the PDF file from the Web browser (in
my case, Netscape 4.79 and Internet Explorer 6.0) to the Acrobat
Reader. It [the method] is incompatible with many PDF file
generators (like reporting tools). So, if you are having these
sorts of problems, just configure Acrobat to use the old, more
reliable, way of transferring the document.” I've never liked
viewing my PDFs inline (inside the browser). If you're given the
option, you might be just as smart to right-click and “Save Target
As” instead of opening it up right then and there.
