I’m using an F77 ultra compact with the old xwhatsit firmware. Everything works great EXCEPT the 6 key, which has a tendency to register late or not register at all at higher calibration thresholds. If I turn the calibration threshold down so that the 6 works consistently, I start to see ghost presses on some of the other keys (which function normally at the higher threshold).
Where would you recommend to start troubleshooting this?
