Thank you both but if all the programmes are turned off as Tony said the Defrag programme said 'turn all programmes of' there is no sound. When I did it I could follow in the manner you describe, but that means Jaws must run, of course. The Hd Failure on desktop may have been pure chance happening next day, but Andrew said it can be very high risk, something to do with Indexes. It left me scared to death to ever do it again. Dorothy Ps sorry for typing I am a bit exhausted now. Also Tony got a Run time Library dialogue on desk top and there is no clue to cause I will try to find out more tomorrow. Thanks again. ** To leave the list, click on the immediately-following link:- ** [mailto:jaws-uk-request@xxxxxxxxxxxxx?subject=unsubscribe] ** If this link doesn't work then send a message to: ** jaws-uk-request@xxxxxxxxxxxxx ** and in the Subject line type ** unsubscribe ** For other list commands such as vacation mode, click on the ** immediately-following link:- ** [mailto:jaws-uk-request@xxxxxxxxxxxxx?subject=faq] ** or send a message, to ** jaws-uk-request@xxxxxxxxxxxxx with the Subject:- faq
