Hi Martin,
Your message to the Radiance-online list came through as a damaged attachment. Can you resend just the text portion of the message -- not as an attachment? In general, it's not a good idea to send attachments to a mailing list. If someone wants to look at your file and you can't put it on a website, you can mail it to people who request it specifically. That way, it doesn't get sent automatically to the entire list.
Thanks,
-Greg
