When I mask off and area and paste in place, a white lien appears around the layer. It isn't there, because when I merge it disappears. I have uninstalled and reinstalled, so I can't really fihure out, what I could have done wrong in the settings. Any advice would be greatly appreciated.
Thanks for your useful reply. ctrl J could work - sometimes. So thanks for that tip. However occasionally I need it the other way. Copy/paste in place. And you are right in 66.67% and 100%, the lines disappear, (though not in the navigator window where the lines remain regardless). Odd, because I never experienced it before. But I guess i can live with it, knowing that it is only somewhat cosmetic. Thank you once againfor your reply.
