I'm on Nonsensikal 16.1 and certain spots on my touch screen seem to not respond when I click them, or I have to click them multiple times. Like I can no longer click on the space to type a message in chompsms, I have to use the track ball to click it. I also have problems clicking the space key, "a" key and "h" key. Is there any way to fix this or is it a hardware problem? I feel like its a calibration thing but I can't figure out how to calibrate it. Any advice is greatly appreciated.
