Multiple jQuery kwicks not working with different number of li

http://jsfiddle.net/YkqKj/1/

This is a demo of multiple kwicks and it works fine.

Note: All the codes are from http://www.jeremymartin.name/projects.php?project=kwicks

However when I have different number of li, then it breaks and when I hover it expands as not expected:

I had the same problem, but i have each kwick in its own tab, so I activated each kwick seperately - when tab was clicked. I know its not the best solution, but I cant find a better one.
