Does the link not work when positioning with a background image?

Question

I have this link

<a href="/Admin/Product/Brands" class="newButton"></a>

Without a class attribute and some text, the link works fine, but when I add the class to apply the background image and button position, the link stops working. It also does not give errors in the firefox console. Any ideas? Here is my css rule for this:

a.newButton
    {
        margin: 5px;
        position:relative;
        left: 310px;
        top: -32px;
        display:block;
        height: 32px;
        width: 32px;
        background-image: url(Images/add-icon.png);
    }

This is an ASP.NET MVC2 application, I am using the latest version of jQuery (1.4.1), and this link is placed inside the container of the jQuery tab inside the dialog box.
