The leech options under the "Discard" area don't work at all. No matter how I set it, it leeches every single tile, even duplicates when told to discard them. This happens in both 4-bit and 8-bit modes. Its been this way for a while, but I thought it might have been the pic I was leeching from. I've tried with a whole assortment of pictures, and none of them deal with the duplicates properly. Also, I'm in windowed large mode if that matters.
