I recently got around to upgrading my computer (late 2013 15" MBP) and all of the little changes are fine except for the fact that when I'm in a full screen program and I open mail it automatically opens a split screen for mail. If I have mail open on another full screen then it will switch to the full screen, but if it's minimized or unopened it will automatically split. This only seems to be the case with the mail app, though I'm sure I haven't tested it extensively. Am I missing a setting? I'd prefer, when opened, for it to open or expand on the main desktop screen rather than split.
Does anyone know how to fix this?
