Hello iandees and thanks a lot! Most of the time I realize when a point gets dragged by mistake, but not always apparently :-D Thanks again for you tutoring.

Ciao dieterdreist e grazie per il tuo intervento riparatore :-)

Hi fmc, thanks a lot for sharing and solving the problem, I certainly did it inadvertently.

I don't even remember making the change. I don't know the area personally, so please feel free to edit as per you local knowledge. Thanks

Ti ringrazio dieterdreist! Un saluto

Thanks Spaghetti Monster, I'll pay more attention.
