No - I missed something. I am new to gdb and sometimes (often?) get
confused.
This is the latest one - and if I understand correctly, again not
triggered.

OK - I evaluated
(setq inhibit-try-cursor-movement t)
(setq inhibit-try-window-id t)
(setq inhibit-try-window-reusing t)
immediately in scratch after starting emacs - is this correct?

OK - running emacs now with all set to t = will keep you posted.
