On second thought, perhaps my problem was (back vs. Return to Index) was a characteristic of my android device. Lately I have been switchinh between my android hand-held, my wifi Kindle, the wife's wifi iPad, two laptops and 2 desktops, I'm just lost...

However, the main point here was that my "back" feature is now working. I use 'back' all the time on the Internet and on the office Intranet, where "Return to Index" does not exist. So I just have a simple, reflexive preference for using the 'back' button.
