There is no such user setting in SA. It was one thought I had, some kind of default maximum number of changes within a certain time limit, but I tried waiting for a while. Sometimes after a wait it worked, sometimes it didn't.

I'll try. But if I take the computer's focus away from the NR screen, when I return it restarts NR and wipes anything which was appearing in the debug pane.
