My Spin SP513-52N's active stylus (model#ACS-032, barcode# NC.LDS11.015) won't let me click, draw, or write on anything. I've tried replacing the batteries and pen nib but it still isn't working. The pen works fine as a cursor but whenever I try to click on anything it does not register. You can see that the laptop registers when the pen is close to the screen but if I try to write or draw nothing happens. I've only had this laptop and pen for under a month, and one day the pen stopped working mid writing. I know there are several others in the acer community who are having the same issue.
