How do I turn off "Auto-Exit"? Does Construct have "Auto-Exit"?

How do I make it so that Construct 2 doesn't exit automatically?

Every few seconds or so Construct 2 exits automatically. It shouldn't exit unless I go up to "File, Exit". Otherwise I'll lose a lot of my progress.

Does Construct 2 have an "Auto-exit" feature that I have to somehow turn off? If so, how do I turn off "Auto-Exit"?

Of course there is no auto-exit feature. Try re-installing the program.
