I've produced a wordpress website that's utilizing a jquery navigation tab within the sidebar. It is a really awesome addition, but my client is worrying that after the page loads, the thing is an incomplete list item load right of 3 tabs. I've really looked also it will it in IE and Opera to date. I do not comprehend the technology at this time, but has anybody experienced this "expensive" using jquery functions? Here's an example page.

You are able to fix that by pushing your nav tabs apart a bit more:

//in glide.css
.tabnav li {
    display: inline;
    float: left;
    list-style: none outside none;
    margin-right: 10px; /* my alteration */
    text-align: center; 

By playing with this margin-right you need to have the ability to solve your condition. Otherwise try having fun with it using Firebug.
