Well, that's peculiar!  Yes, it is.  It is an alpha release of the Tor
project Browser Bundle (TBB).  Firefox, *wget*, and *curl* have no
problem with the files.  (I did try *wget* before I eMailed you, but I
convinced myself that my result was garbage.)

I probably should send a bug report to torproject.org, huh?

When I try to view the file in TBB, it silently shows a blank page.
When I try to save the page, it says it had trouble reading the file.

Aha!  Thanks for that.  That's the first constructive suggestion that
has come my way.  It has solved my problem.  I've posted a *python*
script that does the authentication over at:

I was just going by the number of them (10).

Yep, no reply, yet, though.  DVD with visible label three checks out
as holding the ISO image logical number four.

Thanks for putting my Wheezy upgrade project back on track.
