"Nicky" to turn on Autosave you open CMP then click FILE > SETTINGS > MISCELLANEOUS. In thewindow that opens tick "Auto Save " and "10 Minutes" The only downside to this is that every 10 minutes Surveyor will freeze and you"ll get the dreaded hourglass for a few seconds.The advantage is that if you forget to manually save or have a fatal error, the most work you"ll lose is 10 minutes.....
