Thunderbird has problems notifying of unread eMail when folders are nested.
When one has nested folders in a Thunderbird account the notification of unread mail is not being propagated up to ALL the folders in the chain to the head of the nest.
My Thunderbird often does not mark the account when new email has arrived.
When It does mark the account, all the folders underneath are UNmarked so one has to go on a fishing trip opening each containing folder until the unread email is highlighted.
eg:
AnAccount is (sometimes marked) as having unread email
folder1 (no marking)
subFolder1 (no marking)
subfolder2 (no marking)
subSubFolder (sometines marked)
