I was afraid you'd say that. :-) I've now experimented a bit with the function `A T' command, and I found that for me, the main problem was this code: ;; We want to fetch LIMIT *old* headers, but we also have to ;; re-fetch all the headers in the current buffer, because many of ;; them may be undisplayed. So we adjust LIMIT. (when (numberp limit) (incf limit (- gnus-newsgroup-end gnus-newsgroup-begin)))) In some groups I have dormant old articles, and this means that this will fetch an enormous number of messages. I've just removed this, and had it fetch the previous/next 200 messages in the group. This seems to do the trick most of the time, actually. -- (domestic pets only, the antidote for overdose, milk.) larsi@gnus.org * Lars Magne Ingebrigtsen
