Possible bugs (gnus-demon and switching modes when composing messages)

[Trying to send the message again since it apparently got bounced]

Hello,

Before opening new bugs, I decided to ask here to see if anyone has any
hints on what's happening with me.

1) I usually set-up (gnus-demon-add-handler 'gnus-demon-scan-news 2
nil), to instruct Gnus to automatically fetch new messages from (my
local) IMAP server every 2 minutes.  However, this causes some annoying
effects.  For example, when I compose a message and tell Gnus to send it
(C-c C-c), if during the process of sending the message Gnus starts to
check for new messages on the IMAP server, somehow things get stuck and
the message is not sent.  I often have to cancel the process with C-g,
and hit C-c C-c again.

It is also worth mentioning that if I am opening a large group (e.g.,
more than 2k messages) and Gnus starts to check for new messages, the
same thing happens.  The solution is also the same: C-g, and tell Gnus
to open the group again.

Is this a known bug, and is there a workaround for it?

2) I use more than one account on Gnus, so I have made dovecot put
prefixes on the e-mail groups.  For example, for account "A" I have
"A/Sent", "A/Trash", etc, and the same applies for other accounts.
Depending on the group that I am opening, I tell Gnus to set some
parameters based on the group's prefix.  So if I open a group from
account "A", Gnus will know that when I send an e-mail to that group (or
reply to a message there) it will store my sent message inside "A/Sent".

Well, with that said, the problem is: whenever I change modes when
composing a message, Gnus gets lost and doesn't store the sent message
in the right group (in fact, I still don't know where/if it actually
stores the message).  Rationale: when composing a message that has a
patch attached, I often change to `change-log-mode' in order to write
the patch's ChangeLog, and then change back to `message-mode' in order
to finish writing the message (and send it).

Does anyone see this as well?  Or does anyone have a better workflow to
suggest?

Thanks a lot in advance,
