One more thing. I don't regret buying SteerMouse, but it didn't work either. I uninstalled the LCC using Forklift, installed SteerMouse, set up preferences, etc., then re-booted. Then I did a new backup. Same error message. For now I'll take your advice and change my prefs to "do nothing" after a backup. My Mac will sleep on it's own. If this little issue gets fixed, I'd like to know though.
Thanks again,
Rich
