When I got home, the KP was still on the seat next to me - but the eye-rest off the viewfinder was also on the seat.
I got the same problem on my K3(i) that I still use today, the eye cup keeps unlocking itself, I replaced with 3rd party one with metal parts but also the same problem, then I replaced with the O-ME53 magnified eye cup and it sit tight there, but the rubber eyes relief fell apart quickly just like the original eye cup that's disappointing.
