Hi,
V5
Somehow in the restoration of my bak file I now have 4 raster images perfectly on top of each other, all the same image.
Mouse selection gives me the option of tow of them prefix surface - name of raster and two of them polysurface - name of raster.
Well, at some point you must have created all those, perhaps unknowingly… I suspect groups, you may not know what you are copying if parts of a group are hidden when you make a copy…
