Why does WPF toggle button pulse once unchecked

Question

Within a Desktop app I have a toggle button:

<ToggleButton x:Name="CFStglBtn" Checked="cfsCBox_Checked"
              Unchecked="cfsCBox_Unchecked"
              IsChecked="True" HorizontalAlignment="Left" Margin="5,0,0,0">
    <StackPanel Orientation="Horizontal">
        <Image Source="assets\telephone.png" Margin="3,0,0,0" />
        <TextBlock Text="CFS" FontSize="10" Margin="5,5,5,0"
                   Foreground="DarkSlateGray"/>
    </StackPanel>
</ToggleButton>

For the Checked event I am setting a value and then executing a method FilterView(); //ommitting code

Unchecked state is just the opposite. resets a variable and executed the method again

The question I have is I noticed when I uncheck the toggle button the button continues to pulse or flash ( going from blue to chrome) as if it still has focus. The button will stay like this until another button is clicked.

Is there a way to remove this focus so that when the button is unchecked the button goes back to a unchecked state without the flashing / pulsing color.

As you can see from above this is a standard toggle button no styles or custom
I tested this on just a regular button and I found the same occured when clicked the button will continue to pulse / flash until another button is clicked.

How do you work around this or prevent this effect from happening.

Thank you

not sure why it didn't post but here is the code for the toggle button — rlcrews, Jun 15 '10 at 18:58
Code needs to be preceded by a blank line and indented 4 spaces. Or highlight it and click the "Code Sample" (101010) icon. — ChrisF, Jun 15 '10 at 20:08

Set the Button Focusable="False".

nice easy fix instead of re-templating – cab Jul 20 '12 at 13:10

This is happening because of the button chrome built into the default template for the control. Your only workaround is to re-template the Button. This article should get you started.
