Whenever the error happens again I'll try to capture it, anyway all you are going to see is the rotation button misbehaving as previously explained, being incapable of reaching certain orientations...

It's not something that I can send you in captures, as I would need a video. I could provide video if needed, it happens from time to time and happened again today to me, didn't answer before because...

I can confirm the same problem on a NC220 with the latest firmware, the rotate button skips one of the horizontal positions so it deosn't work as expected, in this case the image is already flipped...
