I have noticed that when some face morphs are applied the NoGlow prop does NOT follow the nose, Poser will only affix it to the HEAD XYZ so when a morph moves the position of the nose then the NoGlow has to be moved manually to assure it is still aligned with the nose. Not sure if this is what is happening with your image but worth looking at. I usually switch to wire frame mode and move in REAL CLOSE and then adjust the NoGlow's X-Y-Z to assure it is still covering the nostril opening, also sometimes need to adjust it's size depending on the face/nose morph used. And then switch back to Texture and Smooth modes and get another view. It does work and works well for me but does need adjusting if the nose moves during morphing...
