If the keys are sticking or not working, try some WD40 on the keyboard. Spray it in the cracks between the keys and work it in good. I saw this as a remedy for misbehaving laptop keys on the internet and it worked for me. Said that WD40 is a non conductor so this is safe.
I have a friend who had this problem. She sent the camera back to Canon for adjusting and they fixed the problem. Pictures are now sharp!
Brings back memories. We were there in 2001.
I'm passing this on to some of my friends!
It's also a great picture for taking closeups --- "almost macro" images.
Well done. Nic landscape and the colors are outstanding!
