I have a canon powershot A40. I've attached the camera via a USB port to my PC. I am trying to use Zoom Browser EX to import pictures to the PC, but am receiving a message that the camera does not work with Zoom Browser. It used to, so I don't know what could have changed. Any ideas? (I also have a Powershot A610 that works just fine with Zoom Browser.) Thanks

Try NOT connecting your camera to your computer.

The best way to download pictures from your camera to your computer involves removing the memory card from the camera and plugging it into a card reader (either built-in to the computer or connected via USB or FireWire). This is likely to be faster than connecting the camera to the computer, and won't run down your camera's batteries.

Once the card is plugged in, it will appear to your computer as a removable drive. You can use the operating system's drag&drop facility to copy pictures from the card to the computer's hard drive, the same way you copy any other files. Or you can use any photo cataloging program.
