Why are the numbers H x W in the Camera settings? Is that normal for a real camera lens?

The camera dialog show us the Negative Format ?x?. Are you talking about that?
That order is consistent with the way people can refer to film format.
"For 35mm film (24mm by 36mm), the diagonal measurement is 43.27mm. 50mm is close to this measurement so it is considered a "normal" lens." - take a look at this link.

- When I dock UV map window then edit and later again undock to close it wings3d gets internal error crash.

I couldn't reproduce it here, but I got it by keeping the UV Editor window docked and closing the project I was using UVmaps.
