This page is just a stub. The index for my Helpful Hint pages is now at my new (4/20) site, WYWTK.com...What You Want To Know.
Many of the links there may well bring you back to this site. (http://www.arunet.co.uk/tkboyd/). Sorry! If it is a particular nuisance for you in some way, please get in touch, citing page "Aru/hh.htm"?
Page has been tested for compliance with INDUSTRY (not MS-only) standards, using the free, publicly accessible validator at validator.w3.org. Mostly passes.
