Another nit-picky one for you, this has annoyed me for ages! If you have no shield (any object), the Shield option on the Control Panel (CP) defaults to ON. When you set the Shield to OFF, then close the CP, when you go back to the CP it is set to ON again... Ideally, I would have thought if you don't have a shield then the Shield setting should be locked to OFF. At the very least, it should default to OFF. Thanks for reading Phil.
