I have a hp Notebook 15.6' and I have been experiencing a lot of issues when trying to use the touchscreen. It works one day perfectly and then the next day it doesn't. I have updated the drivers, disabled then enabled the touch screen, Uninstalled then reinstalled the drivers, calibrated the screen more times than I can remember and yet it still doesn't work properly. There is no physical damage to the screen, nor has it been damaged by water. I can tap the screen anywhere and it works that way, but dragging or pressing on the screen is just not an option. I have attached a pic of me trying to draw straight lines on one Note. If any of you know a solution for this please help!! Thanks
