Happens when the .png is made by something that isn't 100% compatible with Poser (or at least Poser on Windows). First off, check the library folder where the .png file is stored in Windows Explorer or similar: - if there is a .rsr of the same name, then simple delete, or for extra safety rename, the .png file when PP is NOT running, then restart PP and go to that library folder. Poser will recreate the .png from the .rsr and the new one should be 100% compatible with Poser (obviousl ;-) - if there is no .rsr file of the same name, then first run P3dO's RSR/PNG plugin on that folder to create an .rsr from the .png. Then continue as described above. All in all a pain, but be thankful that it's at least readable in P3dO - 'cos just sometimes they are not, then you are down to fixing it in Photoshop by hand...
