I worked around it by using an elisp ‘advice’ snippet another user suggested (http://emacs.stackexchange.com/questions/17112/prevent-org-todo-pop-up-window-from-displaying-in-new-frame-dedicated-window)
Before that I wasted several hours trying to ‘fix’ the problem in various ways. I imagine org is overriding default handling for a good reason, but it is frustrating to have to override said functionality with a code-snippet, which will undoubtedly break at some point while I scratch my head to understand how I can fix it!

I'm not a big fan of Org's opinionated way to handle windows either.
However, couldn't you use `display-buffer-overriding-action' in this
case? It is checked before `display-buffer-alist'.
