OK I figured it out. For everyone else that may get/have the same problem, it is very easy to fix once you know where to look at :-)

Just change the following in the stylesheet.css line 393 :

#productAttributes {
width:100%;
float:left;
border:1px solid #bfbfbf;
padding-left:5px;
margin:5px 0 0 10px;
}

Change to :

#productAttributes {
width:80%;
float:left;
border:1px solid #bfbfbf;
padding-left:5px;
margin:5px 0 0 10px;
}

The width can not be 100% because IE has a problem with it when attributes are used. Hope that helps .
