I appeared to have fixed it, or it fixed itself I think ?!? Scandisk didn't reveal anything wierd that I know of, haven't have to go as far as trying Indexing(yet). However I did Get shot of some of our start up progs, which made the heap of junk run faster, until it threw a wobbly. From what I've learnt about restore points in the last day or so came in very handy.
Thanks for all the input - Woolly
Life with a ZX80 was so much simpler!!!
