emails I have read keep being marked as unread
For some time now Thunderbird keeps marking my emails as unread even after I've read them. I use the setting "Automatically mark as read" but - although it does do that at first - next time i go to the email (either in my Inbox or when it's in Archive) the "Unread (1)" marking is there again. How can I stop this happening? (I've tried changing the setting to "after 1 second, 2 seconds etc but it still happens).
