Layers Are All Invisible

[denzjos]

I think you have build up layers, make the underlying layers invisible and then work on a new upper layer. If one make a selection on a top layer and an underlying layer is selected in the layers dock but invisible and one think that one erase a selection on the top layer then there is information erased on the selected underlying layer but it is not noticed because the layer is invisible. If one select the right layer in the layers dock because one see no result and erase the same selection, then one see the result that one want but the underlying layer was erased.  If one save the picture with some layers invisible then one think everything on the underlying invisible layers is ok but information was erased. I think that happened.
