Whoa, that's a heckuva bit of detective work! :]

I can see again! There's colours and shapes and, and..., minifigs! :]
Everything is fine now. Guess that script you mentioned was the deal.
As for the USR thing, I didn't know that people were making their own
different "flavours" of MSIE. Would've thought MS would've stomped all over
that. When I re-built my system installation after the re-formats, I put on
MSIE from whichever drivers went on first. Most hardware vendors now include
MSIE with their drivers/software. So whomever had the IE5 first in my
reinstallation order won the job. Sounds like it was the USR installation
then that did it. Funny thing is, I've just gotten an ADSL connection and no
longer use the USR modem. Maybe I should re-install IE5. It may shake out
some other problems on the web that maybe I haven't noticed.
Actually, now that I look at that string again:
> Mozilla/4.0 (compatible; MSIE 5.01; Windows NT; 3COM U.S. Robotics)
...I wonder if maybe the USR bit is just simply referring to the hardware
profile that's being used? In other words "MSIE5.01, running on NT, over a
USR modem set-up". In my IE5 settings, I currently haven't added the hardware
profile for the ADSL. So if I were to launch IE5 and go after a link, without
having the ADSL connected, it would bring up a modem dialling dialogue for the
USR. I wonder if adding a profile for the ADSL would change that browser
signature line?
Anyhow, thanx for your help,

Offhand I can think of two possibilities -- (1) your browser config is causing it to send a bogus value for the HTTP referrer field or (2) your browser config is causing it to refuse embedded images sent by a script.
