Which SMIL player have you used?

I couldn't play the document because I don't have the media, but I  
don't see anything obviously wrong with it. In other words: I believe  
(from code inspection) that the document should indeed switch between  
showing section1_image and the rest (everything in par1) when you  
click on section1_image or menu1_image. And the audio should indeed  
continue all the while.

I can suggest two course of action:
1. Try in different players (RealPlayer, Ambulant, GRiNS); or
2. Strip down the document to the basic interaction (the audio,  
section1_image and menu1_image) and work from there.

But: it could also be that there is indeed some problem with the  
intricate details of how restart semantics work, I'm not an expert in  
that area...
