[gnu.emacs.gnus] Symbol's value as variable is void: THRU

bob@tinman.cis.ohio-state.edu (Bob Sutterfield) (01/31/89)

Emacs 18.52, GNUS 3.10 with NNTP 3.7 and NNSPOOL 1.7.  From ~/.emacs:

 (setq gnus-novice-user nil)
 (setq gnus-default-distribution "world")
 (setq gnus-use-long-file-name nil)

and from $LIBDIR/lisp/default.el:

 (setq gnus-nntp-server "")
 (setq gnus-your-domain "cis.ohio-state.edu")
 (setq gnus-your-organization "Ohio State Computer Science")
 (setq gnus-nntp-service nil)

The subject is what I see sometimes when I visit some newsgroups.
Later on, I don't see it any more when visiting the same groups.  Some
groups are more frequent problems than others.  When I try to use
gnus-Group-read-group (space) it happens after "retrieving newsgroup".
I get a bell and I don't get to see the subjects of the articles.
Then I can sometimes use gnus-Group-select group (=) to get a listing
of subjects, after which space works again, but more often = doesn't
do me any good either.

I'm stumped.  Any suggestions?
