Mine shuts down after so many minutes as well. I'm not talking about shutting down the PC, I'm talking about password protecting one particular app. I need to have my PC open at times with no access to certain apps. I'm sorry your imagination cannot accommodate my particular lifestyle. I shall google Gameprotector. Thank you I'm not an idiot and do memorise my passwords, the app I downloaded has decided the password I memorised is incorrect. I hope you do not take such a hectoring tone with all the comments you moderate - I am merely looking for help. M
