Thanks for replies, sorry for the delay in replying.
I must report first that things seem to be back to normal - this morning I ripped the third cd of the book and the thing was done in a couple of minutes, and transfer to my MP3 was done in a flash.
CD - I presume your queries re Task Manager info relate to what's going on during the rip process - this I have not checked, and to be honest I don't really understand the meaning of the info there.
patio - thanks for the link, but my last remark also applies to what's shown there.
One thing -- I have had connectivity problems with my ISP, AOL, caused by a security update of ZoneAlarm (now fixed by uninstalling same) -- this couldn't have had any effect, I suppose?
Anyhow, thanks again for interest.
