John in Kansas, I'll just mention that I was never able to resolve the problem with my old computer and the camera's USB cable. Although the mouse was connected to a mouse port (round socket, FWIW), and I supposedly had two USB ports as well, it turned out it did not matter which one I plugged the camera into, even if I had removed the USB cable from the printer. Plugging camera cable into USB socket would cause the mouse to stop working. I took the camera to a friend for loading onto a CD a couple times, then got my new computer.

Just sayin', Leeneia could run into similar problems.
