I have had my Acer A200 for almost 3 months now and it suddenly developed a problem with it's touch screen. It seems that the slightest movement of the tablet can send it off to other programs or the menu screen. Then there are some areas of the screen that won't activate when they are touched. The tablet has never been dropped or abused. It is kept in a leather case and used maybe 5 hours a week. Has this been a problem with anyone else and if so is there any other solution besides sending it back for repair or replacement?
