Could you explain (and I'm being nice) how my post was not Nice? I am curious so I don't inadvertently offend again. When I said the reason might be dumb there was no implication on my part that this involved anyone else. I truly am puzzled how anyone could take offence.
The issue cannot be searched for in the manual? Therefore it is not obvious in the manual, because the explanation is shown only in an image. The auto indexing won't include it. Now that is an omission on the part of the person who wrote the manual. Having wasted a couple of days wondering why mfp wasn't connecting I feel justified in feeling peeved and calling it as it is.
I spent more than ten years in commercial IT. It takes longer to write a manual than to write the code. But we can't use the software without a manual and the forums are quite hit and miss.
Meanwhile children are dying in Africa which puts it all into perspective.
