I have my inboxes set to display new messages at the top. When I open an inbox, Thunderbird scrolls to SHOW new messages, highlighted in bold, at the top. Or it used to. Recently this behavior has become inconsistent. When I look at Thunderbird, one of my inboxes may show that there are new messages. So I click on the inbox, but no new messages appear in my list of e-mails. I then have to manually scroll up to see them. Something definitely changed here. I can see the case where maybe I've selected an old e-mail message WAAAY down the list. In that case Thunderbird should probably open to that point. Usually, if a message is selected, it's near the top. If that message AND newly arrived messages can be displayed on the same page, Thunderbird should scroll to the top and show me new messages. Is this a setting that can be set?
