Firstly, thanks Dusty for this application. It works under Diablo just as before.

FYI, I find that if I cover the sensor with my thumb in any bright light, especially daylight, then it will not turn off. I have to actually put it in the Nokia cover for it to activate. I presume some light still travells through the skin and keeps it alive.

I always partially slide the tablet into the cover and wait for the notification to appear before finally pushing all the way in.

Just occasionally it gets confused and I need to reboot to reset it. Usually when I have had to use the slider on the top because I want to view in near darkness (or maybe I'm the one getting confused in this case?)
