I ran into the same issue using IE6 and Acrobat5 (I have the full
product, not just reader). The Acrobat IE plugin puts up a dialog
saying "File does not begin with %PDF" - which is a lie, of course.

I cut-n-pasted the URI into Netscape 7 and it worked fine. Nice job,
Walt!

Bill, you should to put a link on the projectpluto site. An HREF tag
on a real HTML page mught not have the same problem.
