#ja-col2 .moduletable_mystyle{

-moz-border-radius: 3px;
-webkit-border-radius: 3px;
}
#ja-col2 .moduletable_mystyle h3{
border-top-right-radius: 3px;
border-top-left-radius: 3px;
-moz-border-radius-topleft: 3px;
-moz-border-radius-topright: 3px;
-webkit-border-top-right-radius: 3px;
-webkit-border-top-left-radius: 3px;
