Hi Eric and Info,
The dotted line (according to Firebug) is caused by the border-bottom rule in this element of css/style.css :
#page li {
background-image:url(../images/bullet.jpg);
background-position:left 5px;
background-repeat:no-repeat;
border-bottom:1px dotted #CCCCCC; /* This line */
line-height:18px;
list-style-type:none;
padding-left:20px;
}
removing the line removes the problem, but I don't know where else on the site it might be in use.
