Hi Chris Thanks very much. So now we know. I must confess that the reason I tend to start by asking technical questions rather than going to Google is that, if the person who writes the explanation does this for her/his living, I probably won't understand the answer. As it is, this is pretty understandable in general, so I'll brave the technocrats in future. My fear is that, if for instance I search for information on CDs, I might get an extract from the Red Book, written by a digital engineer. People on a list sort of know who they're speaking to, and modify their answers accordingly. -- Reg Webb Website: http://www.regwebb.com To post a message to the list, send it to winamp4theblind@xxxxxxxxxxxxxx To unsubscribe from this mailing list, please send a message to: winamp4theblind-request@xxxxxxxxxxxxx with the word unsubscribe in the subject line.
