I'm using Paint.net to make skins for games. I just updated to 4.2.15 version and since then I have a problem with .dds files: before updating if i wanted a transparent part I just had to delete it by selecting and hitting "canc". If i do it with the new version in Paint.net i get it transparent but ingame the transparent part looks black. Is there any different setting? How can I solve this? In case it's something i can't solve, is there a way to get older versions of Paint.net?
