How to restore Mail 5.2 3-column interface?
I'm having problems with Mail 5.2. I can't seem to get back to widescreen layout in my mac mail. I'm not sure what I did, but is there a way to get the 3-way split screen back? I went into Preferences and tried that, but nothing changes. I've read that once you go back to classic mail, you cannot get the widescreen layout back. Anyway, tried the Letterbox app. as well, is not working on Mail 5.2.
Any help would be nice. Thanks!
