I bought the ergonomic keyboard from Microsoft (MXL 00006 or something) and use it on my Windows 10 Insider dektop.
After fillinng in my PIN code using the numeric pad the numeric keys dont function anymore. The keyboard functions normally on other PC's with the standard version of Windows 10. Does anyone recognize this problem?
