I am getting exasperated by the "View" control in Mail: it never seems to hold its settings. In the Inbox, I set it to show the sender, and it keeps reverting to showing the recipient (which is always me, unsurprisingly). Likewise, the Sent mailbox insists on reverting to show the sender (which, also unsurprisingly, tends to be me, too). How can I get it to hold its settings?
