Reader 8 IFRAME inside HTA crashes hta application

Question

Hello,
I'm using an HTA to access my .Net 2.0 site. In this site I'm using an
to view pdfs. In javascript i set the iframes src="/folder/file.pdf" and adobe reader fires up fine inside the
however when i navigate away from the aspx page i lose authentication. This only happens for me when i'm in the HTA. The site works fine when I am using just IE 7 or if I have IE 7 running seperately in the background or when I use Adobe Reader 7.0 with its latest updates. I have checked my Manage Add Ons and I have the ACroPDF.dll enabled and a AcroHelperReaderLink enabled. Not sure what else to do. Please any help.
I have recreated this issue in XP, Server 2003, several computers and even inside a Virtual Machine.

Ben,
Thanks for reply, See below for Version Number I tested against and additional information. 
The Sample HTML has also been run on different OS and Versions of IE 10/11.  And as stated above we have the same issues as the linked post, which is quite simply the following
1) Open HTML Page PDF Display all OK
2) Click the HTML Download link to get a Word Document or any type of Download, and when IE Modal message comes up clicking Save or Cancel has the below result
3) PDF disappears and looks like you left with the Adobe Reader Gray default background, and no PDF.
This is 100% repeatable with the above HTML Code, and the same with and without compatibility mode on or off, one of our first tests.
I have searched high and low in the Web and that the only link I found with the same symptoms is Referenced.
IE Version
Reader
Version 11.0.05.3
Windows
7 Pro SP1
As to the PDF we used I used ones created from Adobe Document Services in SAP from a XDP.  And to narrow this down to an IE and Reader issue, have used the Adobe Reader Release Note PDF (Which is a flat non interactive PDF).
Thanks
Martin
