This happens to me on a regular basis (also IMAP). Usually if I
switch from another folder back to INBOX while there is still some IMAP
communication going on. In this case Claws shows the message counts
from the folder I switched from (unread and total). When I restart
Claws it starts download headers from my INBOX (fast) and then also
wants to download all messages, even though I have no filters defined
that require to get the message body (well, as far as I can tell). The
only way to interrupt this and save hours of downloading messages is to
switch to Offline Mode, after which Claws doesn't feel the need to
download all messages any more.
