When I switch buffers, emacs will switch to an existing frame if the buffer is already opened there.
I found how to prevent that when switching with ido using :
(setq ido-default-buffer-method 'selected-window)
But it's not enough : for exemple if there's a lisp error emacs will automatically switch to the buffer *Backtrace*, and will switch frames if it's already open.
Is there a way to prevent completely emacs from switching to an existent frame?
