I've actually updated to 3.0.2.
2.4.10 works fine (which I've put back on my site).
How can I help debug this - I love this plugin and I think I really love how you're reworked it - I suggest continuing to include a prototype CSS file so we can have the right structure and class/ids ready to edit to match our site; I could add that to my main CSS and save a file download to the client.
Thanks! - Bob
