share facebook,twitter and others problem
 

Please see the below two images.
For Mozilla Firefox, the alignment of share facebook,twitter and others is fine.
But in Google Chrome, the alignment of share facebook,twitter and others run away.
Below is my code:
<div style="float:right;" class="addthis_toolbox addthis_default_style">
<a class="addthis_button_preferred_1"></a>
<a class="addthis_button_preferred_2"></a>
<a class="addthis_button_preferred_3"></a>
<a class="addthis_button_preferred_4"></a>
<a class="addthis_button_compact"></a>
<a class="addthis_counter addthis_bubble_style"></a>
</div>
<script type="text/javascript" src="http://s7.addthis.com/js/300/addthis_widget.js#pubid=ra-4ee9a7bf7f4be905"></script>
Can anyone help me?:(

try this:

<div style="float:right; width:150px" class="addthis_toolbox addthis_default_style">

The code works well. Thanks a lot.:)
