Groups no longer active

[Tony Lam <Tony.Lam+ding@Eng.Sun.Com>]

Upgraded from Gnus 5.6.45 to PGnus 0.94 went pretty smoothly after
modified mail source definition. One thing I do find with PGnus is now
groups in most of my topics are not active any more.

Here is how I usually use Gnus: I have my email/mailing list groups on
level 1 and 2, I also organize groups into topics. I start Gnus by
"M-x n gnus" (n=1 or 2) to read emails, then 'M-g' on topics to read
all subscribed groups under that topics. This worked well under Gnus
5.6.45, with the latest PGnus, 'M-g' on topics does not return any
groups on level 3-5 any more. My investigation so far shows "M-x 2
gnus" no longer active groups above 2.

This new behavior seems make sense, but I think when I do "M-g" on
topics it should still active all subscribed groups under the topics,
and fetch all news messages in the groups. I shouldn't have to do "M-g
3" to activate *all* groups on level 3 and below just to read a few
groups in a topic.

Does anyone else has this problem? TIA for any suggestions.

Regards,

Tony
