Comment subject field too large breaks the page layout
All right I got it. I fixed it in the style.css file

WAS:

.form-text {
    border: 1px solid #ACACAC;
    border-radius: 3px 3px 3px 3px;
    color: #949494;
    padding: 4px 5px;
}


IS

.form-text {
    border: 1px solid #ACACAC;
    border-radius: 3px 3px 3px 3px;
    color: #949494;
    padding: 4px 5px;
    width: 75%;              /* &lt;-- added line */
}
