Many thanks to Dai and Angela ; John ;and Alison. In doubt that any more than a few of my welsh ancestors had enough money or possessions to warrant a will so I do not aim to abuse copyright NLWs digitised wills The idea of screen savers and the Mozilla - which I use - add on is fine for my laptop or home computer so I will investigate. Also I have adobe 6 pro which has features i have never checked. That still leaves me with other peoples computers eg LDS FHCs, libraries. microfiches etc and i have been in several ROs which have no or very few small high-up windows. I have doubts that there will be sufficient light coming from the screen for pics. If flash is unavoidable is it possible to eliminate the glare back?. I recall that about 12 years ago i had an antiglare screen to mitigate the effects of harsh lighting. Anyone tried this or similar? Incidentally, when I visited NLW a few years back i stayed at the adjacent university halls during holidays. Good, cheap, with computer access and in walking distance. Dick fowler
