I'm not sure whether this question belongs here or on the Sony forum, so please forgive me or have the query moved.

The background is that I have been away for some time.
- I am sure that before I went away I had the books in my Sony PRS 650 sorted by author surname, so that Lois McMaster Bujold appeared before Howard Zinn
- As soon as I got back to the internet I upgraded to Calibre 7.44 - I think the version I had was in the high 6.xx - and also transferred the library to a new computer running Windows 7. I had the Sony library software on the old computer running Windows XP, but have not bothered loading the Sony software to the new computer.

The books still appear in the Calibre library on my computer sorted by author surname, but now on the Sony reader they sort by author given name, so that Howard Zinn now appears before Lois McMaster Bujold.

What have I done wrong? More importantly, how do I get the books on the Sony reader to sort by author surname?

I have looked through the Calibre manual and the Sony Manual.
