We just upgraded to Yosemite (OS 10.10.2) with our new MACs and alas, my old letterbox doesn't work, nor, apparently does WideMail. Perhaps Apple actually fixed this and I just can't find how to get the right-hand preview pane with the classic three-column-view. Help please - this is a huge deal for the visual management of email on a large monitor. Regards, Rachel
