My Mac has Emacs v22 and it only splits horizontally when I type ^x-2.
My Linux system has Emacs v24 and it splits vertically when Emacs thinks that's a better choice. The problem is, I don't want it to split that way. How do I prevent emacs from splitting vertically?
C-h k C-x 2
. Is the key properly set tosplit-window-below
?
