The camera has been intermittent with the "Err 99" error since I cleaned the lens contacts and contacts on the body of the camera. I gave them a good cleaning and it's only happened once since. We checked our camera receipt and the camera was purchased on February 20th, 2010. So, it was just 3 days short of being outside the warranty when we contacted Canon. The camera has to be shipped to Mississauga on Tuesday so I'll be without for a couple of weeks at least (depending what Canon tech department finds).
I've been taking a lot of pictures around the house to try to get the error to return, here are a couple of samples (none with my youngest daughter in this batch...couldn't catch her while she was awake!).
