To any touch. I can force the shut down slider to show up, but it will NOT respond. I can make the start screen light up,but again it will not let me slide to open. Just before this happened I got a " LOW MEMORY ' notification. Can anyone help? OH,my iPad and Acer, Win 8 are linked by Dropbox and authorized in iTunes. Does that help? anyway to get rid of my photo's or data from iPad without going in through the iPad screen? THANKS! Diane.
