I'm subscribing to a Gmail account, and while the ''All Mail'' folder is selected, new incoming messages don't appear in the Threads Pane automatically. I have to manually navigate away from the ''All Mail'' folder and back in order for it to display those new messages. But, this is not the case with the ''Inbox'' folder; new messages appear automatically. How do I make the ''All Mail'' folder behave like the ''Inbox'' folder? Thanks.
