thanks, javalord, for the tips. I think I will replace the DVD after ordering a new one from the link wombar provided.
It probably is easy but I do have a friend to help - pathetic isn't it ? I'll pay attention so I can do it myself next time !
re mags maybe "which computing" is better ? they don't take advertising - in fact I think Which is not for profit. I get the ordinary which mag but not the computing one - drawback is of course its relatively pricey !
