hi to all,
already seen a lot of helpful advice.
currently limping along with my computer, a sony vaio laptop running windows xp. computer is old like me, so is allowed to have hissy fits every so often! until recently all ok, then the dreaded blue screen of death. now working my way through things i haven't had to think about for years. progress is slow, but now i've discovered this site, i think i could speed up a bit.
so i'm very pleased to have found you all and alll your answers
many thanks to all
