Interestingly, the problem went away. Maybe on it’s on, or maybe from applying pressure with my finger on the right side of the display. I got it to come back once and to go away again one last time (thus far). I can not cause the mirror inversion since then.
I only tried that because I was holding it on that side when the problem first occurred. Now, my guess as to the cause is a connection internal to the e260v2 is showing it’s age and got a life extension from the finger pressure. Se le vie. I will use it while it last. Into the sixth year isn’t bad.
Thanx for your advice and information.
