Sonos controller prevents standby / sleep / screensaver

Just wanted to let y'all know that Sonos Controller 4.2 on Windows XP prevents the computer from putting on the screensaver / locking your computer / going into standby/hibernate, or turning off your monitor.

This is only so when music is actually playing.  If you hit "pause" on the controller, the computer can do its power-saving tricks.

Workaround: pause the music or set the sleep timer in Sonos Controller.

I don't see a way to change this behavior, let me know if you find one.
