Ah yes, the pursuit of the proverbial "RED X", as espoused by an American
quality control guru...!
Don't ask me for his name, as I've forgotten it since I retired---but the ONLY
sure-fire way to confirm the existence of the RED X is to be able to turn what
you're attempting to "fix" either off, or on, by "activating" or
"de-activating" it.
So simple! Removes all of the other "noise" that could be interfering with any
true root cause.
