I have a S95C which I use for a computer monitor.  Occasionaly the screen saver turns on and asks me if I want to 'Continue Watching'  .  When I first got the TV i just pressed the middle round button on the remote and it continued.  That button now does not let me click the option to continue watching while the countdown starts to auto-shutdown.  To keep the picture on screen, I must press the home button on the remote which then shows my menu with the HDMI screen in the little inset.  Then clicking the middle round button brings back my screen.  I suspect this is caused by a software upgrade on the tv as the button does work, just not in the way I would expect.  Has anyone else experienced this?
