This behaves differently than periodicity checking. Once the bug occurs, EVERY pixel is returned the same from that pixel on until the end of the image. If you change passes mode or image resolution, every pixel in the new image will be the same. If you do a save immediately upon hitting the bad pixel (there may only be 1 or 2 such pixels in the whole image!), exit fractint, and then restart with the saved image, the image will continue normally.

Hmmm. That *is* an odd one. Good luck. I wonder if a pointer is getting trashed. Are any (user-variable) parameters altered? - Bud
