I've had my R14 for about a year and am very happy with it overall, but the touchscreen has started acting up recently. It sometimes goes mad and looks as if a ghost is tapping all over it really fast! If the background was a picture of a lake, you would think it's animated and rain is falling on the water surface. The tap marks appear really fast and all over the screen, but they're more concentrated around the edges. It gets almost impossible to use the keyboard and/or the touchpad as the "taps" cancel every command/click before you can complete it. I have to shut down the laptop manually and power it on again to fix it, but this has been happening more often over the past week and I'm now concerned because the manual reset is affecting my data and my hard disk. Any suggestions?
