[Orgmode] Agenda View window splits vertically

[Juri Artamonov]

Guys,

I'm newbie in emacs. Could please advice. Somehow I get my agenda view appears vertically, i.e from the right side from my org file.

I open org file then press C-c a and I see "Agenda Commands" in the window to the right, not to the bottom as it was before. Could you please advice, how to make it back and make agenda view open horizontally?

Thank you,

                  Juri.
