Yeah, save_dialog_prefs would need the parts of configuration_save() that
opens and closes the file of course :-)

I'm afraid I didn't think this through enough, any change to a setting will
update the project file and get it a new timestamp so you would be getting
the message all the time.

I guess that if we allow multiple openings of the same project (and I can't
see how we can prevent it) then when a setting is changed it will change the
project file.  Its probably not really a problem, it was the race when
multiple instances closed that was the problem.

ATM the project saves the session files in the project each time a setting
is changed, that would need fixing.

As I said post 0.19 a reload dialog could be nice so instances could be

Yes this will remove the race for the project file on closing multiple

Also I've just discovered that if I close a new_instance with files open
when the main instance has a project open, on closing the project, the main
instance's session matches the session files that were open in the

Clearly the main instance is re-reading the conf file and getting the
session files written by the new_instance.  Saving session files only in the
main instance will fix this too.
