Dennis, Hakugin, I tried your scripts and had to alter a typo here or there, but once the basic errors disappeared I had the same error message. "Conflicting edge detection already enabled for this GPIO channel".
As much as I despise web based bulletin board systems I registered on the Raspberry Pi website to ask for help as well. Appreciate the effort you both put in those scripts. Will keep working with them and the general points you made. Still checking here and am discussing all this in the Raspberry pi newsgroup. Thanks to the several people who mentioned it. Again, still listening here if anyone has any more to add. -- https://mail.python.org/mailman/listinfo/python-list
