we now use

(require 'switch-to-new-buffer)
(let ((default-major-mode 'org-mode))
 (switch-to-new-untitled-buffer))

in site-start.el and also have replaced switch-to-new-buffer() with your new routine. Emacs starts with an "untitled" buffer in Org-mode, but does not ask when closing the buffer with unsaved data. If this did work (it does not), what would happen to the "untitled" buffer if the user switches "manually" to another major mode?

Many thanks in advance.
Warm regards,
 Stefan
