Trouble viewing embedded document?

Some users see nothing but a blank space where embedded documents should be. If you are one of those users, try this:

Open another tab or window in your browser and go to google.com. Look for a black bar on the top of your browser window, and see if your Google log-in name appears on the right.
Google bar with active account name

Pull down the menu and log out from Google.
Google account menu pulled down

When you're logged out, the end of that bar should read "Sign in".
Google account menu with no one logged in

Come back to the window with the embedded document and reload it.

Now you should see the embedded document. If not, download the document using the link above the blank area.
