If the light shapes were "decagonal" or "nonagonal", this would indicate that the problem was caused by lens flare. A 9 bladed aperture in your lens would create a "nonagonal" (is this the right word?) shape in extreme lens flare situations. If I can recall youe original problem. it does sound like you are describing lens flare. This happens when a very bright light source is either part of the picture, or is in view of the lens, but just outside it's angle of view. A lens shade might help in the future, but I usually find them to be not too useful as "shades". Dan C.
