A long, long time ago, I had a woman call me and say, ""I was updating the PR check register and realized I hadn't printed all the checks. I couldn't stop the update so I unplugged my computer."" In the middle of the update.... Now this was the wife of the owner doing this at her kitchen table in her bathrobe, I'm fairly certain. Too bad they did not have a backup. (They are no longer a client, BTW.)
