Thanks John

That's got me a bit further down the line. There are still several stops and the space bar need to be pressed to:

1. Start the animation on the first page
2. Then to move to the next page
3. Then to start the animation from the next page

Is it possible to remove the need to press the space bar to start the animation or to turn the page?
==============================
The audio is a bit different. The user has to click on the sound object to start the play back. Can the playback be started when the page slide is first displayed ?
I have looked at the possibility of including the audio file in the animation - but animations are restricted to *.wav files which are very short sound files. The audio file with the commentary is a *.wmv file which is a minute or so.
