Oh no. I've been shadowing a problem call hours in I noticed they had accidentally clicked in a Cmd window, which pauses it. They had been waiting on a paused screen for hours.

@SwiftOnSecurity technically I think it only pauses if you select some text, but it's easy to do accidentally if you click and drag just a little bit. It's left me with a compulsive need to hit Esc about a dozen times every time I focus a long-running cmd task, just to make sure it's still going.
