Ahhh, I found the problem. Turns out my browser is okay -- the problem was my firewall software. By default it blocks referrer strings between different websites.
In case anyone else ever has the same problem -- I added "tolkienlibrary.com" as a trusted site:
Information About Your Browser: PERMIT
Information About Visited Sites: PERMIT
(This is in Norton Internet Security 2005, but I think most firewalls have similar settings.)
So I see we have a comfortable lead now, 38 to 32! :happyelf:
