I do understand what you're saying, and I agree. However, I can't explain it any other way. It's a fact. When I removed the CHDK files from the SD card the camera began working normally again. I will try to install CHDK in the future again, but right now I'm not that advanced, and I don't need the features that CHDK unlocks. What I do need to do, is to learn everything I can about the standard operation of this camera, before I get into anything more complex. Thank you for your quick replies though.
