Here's a small hint about Kindlegen. Stay very far away from it. You need to go back to DOS to run it and it bollixed up my file. Calibre got it 100% correct. So time to get an output file from Kindlegen--5 hrs plus lengthy phone call to computer genius friend. Time to get output file in Calibre--about 2 min. while I was listening to lecture by computer genius friend on hidden codes.
