I just tried this using 2.8.1pre.4 and I didn't receive any error. 

What version are you using?

Right here I receive the login/password page. 

I figure that isn't correct, as I assume following the "Enter" link should
read the login/pw from the cookies stored.

No problem at all.

I only have Netscape (4.5PR2, Linux), and it all seems to work properly.
Going back to the "Enter" link under Netscape takes me to the grid page,
however, not the main login/password page that Lynx does.

My trace file looks similar to yours:

I'm not sure why you are receiving a 400 error from what seems to be the
exact same info sent to the server as my copy is sending -- however, that
extra line in the headers before the TVG_EDNAME pair seems to be why it
isn't logging me in instantly -- the TVG_USER cookie with the
name/password is right after it, and I assume, not getting parsed.

I'll take a look around the source, but it'd be nice if some other people
did as well in case this is a limitation in the length of headers being
sent (does spec allow headers with breaks of some sort?) -- I'm only
familiar with the cookie handling code.
