AddThis

AddThis CSS is being applied to all links on my site, not just AddThis buttons

This style sheet is being applied to all of the links on my webpage:
http://s7.addthis.com/static/r07/widget088.css

I causes several undesired effects to links on my site.

Specifically:
#at3wintoolbox a:hover, a:focus {
background-color: #3DADFC;
color: #FFFFFF;
cursor: pointer;
font-weight: 400;
opacity: 1;
text-decoration: none;
text-shadow: none;
}

Why is is being applied to my entire site? Please fix this. It started just recently.

You can see that it is being applied when I inspect the element in Opera, here is a screencapture:
