问题
This is about the (mootools-like) kwicks Jquery plugin: http://www.jeremymartin.name/projects.php?project=kwicks
I have the same problem as this guy here jquery kwicks issue (kwicks for jquery works fine on test site but not on live site) but in my case I know what the problem is, I only can't find an answer yet, and the Kwicks plugin is no longer under active development.
I believe the problem is with the Jquery version. This plugin works great with 1.2.6 but on 1.4.2 it just wont work. I have tried to check the code for the plugin but I don't know how to upgrade it to be 1.4.2 Jquery compatible.
I have never used 1.2.6 so I don't know what I need to change to make this work for 1.4.2.
Please help. Thank you!
P.S> Please find below the source code for the plugin (Jquery 1.2.6 compatible).

Thanks to Nick Craver and http://jsfiddle.net/ (see comment on original post), I found the problem! The packed and minimized version I downloaded from the project site seems to have a problem cos now I'm using the unpacked version and it works perfectly.
Download the unpacked version (or just copy the code as I have pasted in the OP above) and you should be good to go. Then pack it yourself if you want ;-) http://kwicks.googlecode.com/svn/branches/v1.5.1/Kwicks/jquery.kwicks-1.5.1.js
StackOverflow rocks!

I have the same problem. In FF, using jquery 1.4.2 the wkicks plugind dont work. I change the line 28
Old line
var kwicks = container.children('li');
Replace by
var kwicks = container.find('li');
And then the plugin works fine in IE and FF using a jquery 1.4.2 version
