Sticky Accordion issue

I’ve installed a theme, StarDesign, which uses Kwicks accordion. When I set “sticky: true” in the JS the accordion distorts and acts in a strange manner.

Can someone give some insight into what might be going on here? I have a fairly urgent deadline of Friday (2 days time) so prompt responses would be greatly appreciated.

Current code:

(function($){
	$.fn.kwicks = function(options) {
		var defaults = {
			isVertical: false,
			sticky: true,
			defaultKwick: 0,
			event: 'mouseover',
			spacing: 0,
			duration: 500
		};
		var o = $.extend(defaults, options);
		var WoH = (o.isVertical ? 'height' : 'width'); // WoH = Width or Height
		var LoT = (o.isVertical ? 'top' : 'left'); // LoT = Left or Top
		return this.each(function() {
			container = $(this);
			var kwicks = container.children('li');
         /* added by codestar */
			var normWoH = (o.width/kwicks.length); // normWoH = Normal Width or Height
			if(!o.max) {
				o.max = (normWoH * kwicks.size()) - (o.min * (kwicks.size() - 1));
			} else {
				o.min = ((normWoH * kwicks.size()) - o.max) / (kwicks.size() - 1);
			}
			// set width of container ul
			if(o.isVertical) {
				container.css({
               /* added by codestar */
