WPF controls get focus in XP with dashed boxes

All buttons, ListBox, and other controls have a dashed box when they get focus. Select the 523 button to qualify for the dashed box.

　　

I add a style that adapts to all the buttons in App.xaml, not valid

<style targettype= "{x:type button}" >
<setter property= "FocusVisualStyle" value= "{x:null}"/>
</Style>

The current workaround can only add code in the absence of a control or control style:

<setter property= "FocusVisualStyle" value= "{x:null}"/>

A little bit of trouble, who has a better way?
