I have always used the Recent Mail window. In the current version, I observe that I can get two well-separated emails highlighted at the same time although I have only chosen one. The second highlight sometimes stays in the same relative position in the window; this means that it moves as I move down the list. This does not always happen. As I write the subject of the email that is open, is outlined in blue while another is blocked in blue. When I trash the open email, the block moves down the list one place. While this may not be particularly serious, it is somewhat disconcerting. Has anyone else seen this?
