I had an HP Envy which I promptly returned because of how unresponsive it was and huge number of problems I had with it. Instead I got a Samsung ATIV 500T and it has been much better with one exception. When using it as a tablet on Facebook for example, when I touch a text input area the keyboard would pop up for a second and disappear. It would do this 3-4 times until finally it would stay up. This occurred on the HP as well. Does anyone know how to fix this?
