After more testing, I have confirmed that v2.3.7 is doing something nasty with my Seen database. To verify, I have done the following experiment (using Outlook): 1) Open my INBOX. 2) Mark a message as Unread. 3) Open INBOX.test 4) Open INBOX. The message is no longer marked as Unread. If I look at my xxx.seen file, it gets larger after each of steps 2, 3, and 4. I am using the default database type, which is (I think) skiplist. I am not using auto-preview or reading the messages. +++++++++++++++++++++++++ [I suspect it may have done something unsavory with my Seen data, but unfortunately I didn't save a copy so I can go back and make sure. I will continue to investigate.] Larry R.
