Some issues... Fixes Here

Great theme!
But it breaks in Opera 9. This is with a problem with the search box. The file search-box.tpl.php has a

tag that is not needed.

Also, there is a problem with the comments margin. To fix that, the style.css must be modified en the comment's margin (set the left margin to 0):

.comment {
position:relative;
width:595px;
margin:0 0 0 151px;
padding:0 0 0 10px;
border-left:1px solid #999999;
}
