Whacked It

Googling E18 led to hours of reading about the Canon problem. Finally I saw a link that said I FIXED IT and read that this guy was about to toss the camera when he read to turn it on and whack it two times with your palm next to the USB port. It worked for him. It worked for me. I won't trust this camera on a vacation or special event without a backup, but we are back in the baby picture business for now.
