Ah! Good to know, thanks for pointing it out.
I can't really afford to go an buy all the various Kindle versions to test on so I rely a lot on the Previewer - and I put a disclaimer on my amazon book's page that it's only guaranteed to work on the Paperwhite.
I wonder what the number/percentage of Kindle users are on the Fire? It might be worth my while to invest in a Kindle Fire if it's large enough ...
