The thread prompted two thoughts apart from the realisation that everything I could have suggested already has been;

1   There are some Mudcatters that qualify for the categorisation of "Mudcat Treasure", and
2   All those of us old enough to have had to deal with old computer languages, Operating Systems and hardware have had enough trials (our own and others') to automatically behave in ways that help maximise conservation of effort, while newcomers are too easily gulled into believing that the computer is there to help in all circumstances.

Sigh!
