all the help screens for my kindle to do with frozen screens say to turn it on and off again. This simply does not work. There are tantalising links to other pages but, hey, this being the modern age when nobody does anything that is useful, constructive or businesslike, the links all lead back to the original advice - turn it on and off again. Utterly useless. How many people get paid to construct illusory comforting forum/websites etc? Save the money and get people in that can actually do some proper work - just a suggestion. Certainly not happy.
