I swear that when I first installed the software I was downloading only the new images from the camera into my PC. If I take new pix and download them, only those new ones would download. Now that's changed and all pix download again, resulting in many unwanted duplicates in the PC. I've uninstalled the software, reinstalled it, made sure the box for "new images only" is checked in the camera window preferences, but it still downloads all the pix in the camera. What's up? What's the fix?
