No, WRONG context. I am explicitly turning it off. Whether that is the same as removing it from the launching cli, I haven't tested. But I suspect that if I removed --detect-pua, it would still default to on. Correct? At 78 yo, I try to play by the rules, but the rules do need to be stated clearly. Thanks Chuck.
