I am running 9.10 firmware and the last few rides I've been riding and my Edge just locks up whereby all numbers stay the same, and any button pushes seem to make a noise but nothing happens, this includes the stop/start or even the power button. What I do to fix it is hold the power button and the lap button whilst riding and the Edge reboots and I can continue the ride from there. The good thing is that the ride is not lost and only the part of the ride where the device has locked up is not recorded. Is there anyone else experiencing this, any ideas to resolve? It has only really started happening recently.
