Hi Ralph thanks for the warm welcome. Thanks for the information re previewing the slides - I had hoped that preview would take up the sound track from the same point but presumably this is impossible??? If you have any further suggestions, they would be most welcome Sorry for the delay in reply - I have been out of commission for a few days.Many thanks Stan Hi Guido Thank you too for the warm welcome and your suggestion regarding Audacity. I have downloaded it and look forward to trying it out. Many thanks - sorry for the delay in replying, but as I said to Ralph I have been out of commision for a few days. Stan
