If the problem is that the columns wrap under each other at narrow window widths, change the following in template.css at line 299:
ul.cols-2 li,ul.cols-2-ul,ul.cols-3 li,ul.cols-3-ul,ul.cols-4 li,ul.cols-4-ul,ul.cols-5 li,ul.cols-5-ul,ul.cols-6 li,ul.cols-6-ul,ul.cols-7 li,ul.cols-7-ul,ul.cols-8 li,ul.cols-8-ul
{
float: left;
padding: 0% 0.5em;
white-space: normal;
}
To:
ul.cols-2 li,ul.cols-2-ul,ul.cols-3 li,ul.cols-3-ul,ul.cols-4 li,ul.cols-4-ul,ul.cols-5 li,ul.cols-5-ul,ul.cols-6 li,ul.cols-6-ul,ul.cols-7 li,ul.cols-7-ul,ul.cols-8 li,ul.cols-8-ul
{
float: left;
padding: 0;
white-space: normal;
}
