Thanks for the information. I use Screenshot Captor a fair amount , so would like to solve this. I went back on the machine and tried to duplicate the problem, but it has not reappeared. I only use SS Cap to pull still frames off a recorded video, and did it several times just now but only found one entry in the places in the registry. Below are the registry entries where I had to delete hundreds or maybe a K of duplicates:
