[Orgmode] Keeping agenda window

[Radosław Grzanka]

Hello,
  I'm pretty new user of emacs and orgmode. Here is my problem that I 
tried to solve for couple of days now.
When I open agenda window it splits my frame horizontally - I browse my 
agenda and that is great.
    However, if I follow the link to one of my outlines it opens in the 
window of agenda - this is not what I want. I want it to open in my 
upper window (preferably moving cursor and focus there) and leave the 
agenda window intact so I can still see it.
  I've browsed 'org-customize' but foud no variable responsible for 
such behaviour. Could someone point me in the correct direction?

Org-version 6.36c Emacs version 23.2.1 on windows.

Thanks,
  Radek.
