Why does a Save As operation leave the file unchanged?
This is usually because the image has been saved with a different file name or to a different folder, and DeBabelizer Pro is opening the original image. One way to determine which file DeBabelizer is opening is to check the dates of the files and make sure you are opening the one you just saved. Also, check the save destination for the file (set in the Save As dialog), and check the Naming and Save options to determine what conventions you most recently used.
