Why does my Macbook self - logout when I leave the house?
I bought iCam mobile for my iPhone from Apps on my iPhone and I bought iCam for my Macbook from Mac Apps. I set them both up and turn them both on before I leave home making sure with Preferences>Energy Saver that the Computer and the Display on the Macbook don't go to sleep while I am gone allowing me to monitor my residence. Assuning that there is no movement at home because I get no notifications on the iPhone I imagine all is safe. When I get home I find that my Macbook is in Login mode. I am not a computer wizard and admit that my Macbook may not be set up right but I am sure I have taken all the possible precautions before hand. What am I doing wrong?
MacBook, Mac OS X (10.7.4)
