Thanks for the report. I still use the D40 but had a scare earlier this summer that made me think I might have to replace it. I never did make a decision as I was able to get it working again. It got wet in my day pack and showed errors unitl it dried out. For the next month I had problems with the camera not shutting off and found it was due to a false reading from the fn button. I worked it by pushing the button dozens of times and seems to be working correctly now. Whew.
