Yep, the script currently will overwrite any CSS class names you define within each tab, since what it does is assign the currently selected tab a class of "
.selected", and those that aren't a blank class
"". Until I have time to update this script to not be intrusive like this, the only quick way to overcome this is to disable the "highlight current selected tab" feature, by commenting out the below line inside the .js file:
//this.getselectedClassTarget(this.tabs[i]).className=(this.tabs[i].getAttribute("href")==tabref.getAttribute("href"))? "selected" : ""
