I was all set to render my infallible opinion until I read below:

Hm.  Did you by any chance copy your ~/.pan2 directory from the older
machine to the newer one?

Often an odd problem with just one group is caused by corruption
of the group's data in your ~/.pan2 directory.

For example, sci.electronics.design should appear in 'groups.xov'
with some cryptic numbers.  Try deleting that one line.

$grep electronics.design .pan2/newsgroups.xov
sci.electronics.design 39815 39813 6:1024988 3:1024988 7:1024991

Pan creates a file 'newsrc-n' for each newsserver that it knows
about:

$grep electronics.design .pan2/newsrc-*
.pan2/newsrc-3:sci.electronics.design!
.pan2/newsrc-4:sci.electronics.design!
.pan2/newsrc-5:sci.electronics.design!
.pan2/newsrc-6:sci.electronics.design! 1022878-1022879
.pan2/newsrc-7:sci.electronics.design!

You can see that only one of my newsservers carries that group, and
that I enjoyed reading the two articles numbered 1022878 and 1022879
on that particular server:

I found the two snippets above in ~/.pan2/groups/sci.electronics.design

I can't explain the details of all those numbers, but I know they can get out of
sync for various reasons like power failures and other inevitable annoyances.

If you delete your ~/.pan2/groups/sci.electronics.design, you will need to fetch
all of those article headers from scratch -- but it might fix your problem.

Perhaps Duncan will have already replied in the time it took me to write this.
He will have wisdom to share with both of us :)
