Hi Simon, thanks so much for your response.

I would be happy to do that if it is not too difficult, but it sounds like NCX would make this a heck of a lot easier -- if I knew how to use NCX properly.

I’m looking at an OutBox entry I created just now with Mail V v5.2.2 and it definitely has an AIFC attachment, but as I say until I get NIE to recognise my ethernet card I can’t verify that it actually gets sent as such.

Yes, I definitely was choosing AIFC.  Both it and "Sound Frame" send as .nwt attachments.  

A view inside the .nwt as sent with "AIFC" does reveal some text to indicate that it is something like an 8 KHz AIFC file, but it still seems to be encoded in some kind of Newton paper roll / soup format I don't fully understand.

Thanks.  I used NCX 2.0.4 as I am still on 10.6.8 and did not see any way to do that.  Does this require a newer version?  If not, I can try again.  I maybe did not try dragging a Notes item, though I did try various other forms of clicking.

Cheers,
Tim
