When I single step through the code below, it sends back the PDF file that
is retrieved in the line fm.GetAccountPDF(...). When I run without single
stepping, I get the master page for this page. I have actually saved the
file returned by IE 7 as a text file and opened it in notepad, so I have
confirmed that it is indeed the page master being returned. The code is in
the code behind file for the aspx page and is called directly from a link on
the page. In all cases, the PDF file is correctly created on the server and
I can open it directly from Windows Explorer. This code is actually
slightly modified from the code in MS TechNet article 812406

What am I doing wrong?
Thanks,
