Would it help if I posted a scanned-in image showing the green blotches on the printed photo?  My gut feeling is that when I scanned in the patches, although there were no errors, perhaps some were not read right and in affect, made a bad look up table, so whatever color it meant to print, printed green.  I know there is a way to look at the data file but there has to be a simple explanation. -  Jim
