If you have enough thumbnail rows to cause the links to break to more than 1 line, you can assign box porperties to the link CSS to prevent them from overlapping:
#p7GSnv {
margin: 0;
padding: 0.25em 0;
font-size: 0.75em;
background-color: #FFFFFF;
border: 1px solid #FFFFFF;
color: #333333;
text-align: left;
width: 400px;
line-height: 2em;
}
