Hi I have an Mac 10.7.3 I have been having issues with my wireless keyboard. Whenever I use Lighroom adjustment brush for a prolonged period the keyboard stops working - battery 100% When I placve new batteries/ and or wait for a period of time and press the button on the side of my keyboard the keyboard starts working most of the time. Yesterday I bought Apple's batteries cause I heard that only their batteries are foolproof. That is the background. I decided to check the battery a few moments ago and it was 100% - no issues with the keyboard - but on going further found that the bluetooth keyboard is not discoverable -see screen shot. Be grateful if you could advise how I can make it discoverable - and if is not discoveable, why is the keyboard working?
