Unread mails marked as old

[Manuel Carro <mcarro@fi.upm.es>]

Since I have seen some mails regarding IMAP access and changes in it, I
would like to ask for opinions on a problem I have been experiencing
intermitently.  I already mentioned it in a previous message, but
apparently there was no idea as to what could be happening.

I have a setup in which I *download* mail from several servers (IMAP and
POP servers in my case) to my laptop, split in groups, and then I
accessed locally.  I have some 270 groups now.

I have a virtual group which puts together all mail from all the other
groups - therefore what I see there are unread and ticked mails.  But
sometimes (and, I would say, in connection with reading that virtual
groups, but in a very non-deterministic way) unread articles are marked
as read, ticked articles are unticked, and old read articles are
unmarked and appear as new.  I have not found a patter why this happens,
but it is a major nuissance because I partly use No Gnus to organize my
work and keep track of things remaining to answer / act upon.

Does anyone have any idea of what could be going on?  Any clue as to
where to start looking for a sympton?  I am running No Gnus v0.11 from
the git repository (updated some 4 days ago or so).

Thanks for any hint!
