I have been using this great plugin for a couple of months now.
After the latest update, users have started to complaint about being unable to see the embedded documents if they use IE.
Firefox and Chrome work fine. The problem is only IE (why I am not surprised?)
I think you’ll find that if you change your cookie settings in IE8 to “allow all,” it works. Obviously this is not a good solution, but it does seem to indicate a compatibility problem with google’s viewer and IE8 in default configuration, which blocks a cookie the viewer now requires.
(If you get a chance to test this theory on your end, I’d be interested in the results.)
You are absolutely right.
I checked Internet Options—>Privacy —>Advanced—>Override automatic cookie handling and now IE8 is displaying the embedded files.
It was not necessary to check Always allow session cookies
