Same. Also the problems I've encountered when one file tries to autosave, triggering a calculate before save, when I am actually working in something large that is calculation sensitive (manual calculation mode is on), and my whole application freezes/locks because it calculates when I'm not expecting it. Always happens 5 minutes before a deadline too. So yeah, disable that.

It's also a Workbook level setting so, you might have it turned off, but someone sends you a file with it enabled. For that reason, I have a macro that disables it at Open for all files (same for calculate before save, I really dislike that setting too).
