title: WPF displaying differently on different computers
body: <p>I am running Windows XP on my computer, and another computer also is running Windows XP.</p>
  
  <p>In my WPF application, I've changed the styles of my buttons to appear as if they are not highlighting when rolled over, clicked, etc.</p>
  
  <p>On my computer, this is the behavior that is occurring.  On the other Windows XP system, I am seeing some outlining of the buttons with I roll over them or click.</p>
  
  <p>Any ideas on why this is happening?</p>
  
  <p><strong>EDIT</strong></p>
  
  <p>Here is the Button itself</p>
  
  <pre><code>        &lt;Button Click="Next_Click" Width="100" VerticalAlignment="Center" BorderThickness="0" BorderBrush="Black" Background="Black" IsTabStop="False" DockPanel.Dock="Right" HorizontalAlignment="Left" Height="154" Name="NextOffers"&gt;
              &lt;Image Source="Images/offer_right_arrow.jpg" Width="100" Height="154" MaxWidth="100" MaxHeight="154" HorizontalAlignment="Left" VerticalAlignment="Top" MinWidth="100" MinHeight="154" &gt;&lt;/Image&gt;
          &lt;/Button&gt;
  </code></pre>
  
  <p>Also this Style, too.</p>
  
  <pre><code>&lt;Style TargetType="{x:Type ListBoxItem}" x:Key="ListBoxItemStyle"&gt;
      &lt;EventSetter Event="PreviewMouseLeftButtonDown" Handler="ListBox_MouseLeftButtonDown"&gt;&lt;/EventSetter&gt;
      &lt;Setter Property="FocusVisualStyle" Value="{x:Null}" /&gt;
      &lt;Setter Property="Template"&gt;
          &lt;Setter.Value&gt;
              &lt;ControlTemplate TargetType="ListBoxItem"&gt;
                  &lt;Border Name="Border" Padding="0,0,2,0" SnapsToDevicePixels="true"&gt;
                      &lt;ContentPresenter /&gt;
                  &lt;/Border&gt;
                  &lt;ControlTemplate.Triggers&gt;
                      &lt;Trigger Property="IsSelected" Value="true"&gt;
                          &lt;Setter TargetName="Border" Property="Background" Value="Black"&gt;&lt;/Setter&gt;
                      &lt;/Trigger&gt;
                  &lt;/ControlTemplate.Triggers&gt;
              &lt;/ControlTemplate&gt;
          &lt;/Setter.Value&gt;
      &lt;/Setter&gt;
  &lt;/Style&gt;
  </code></pre>
  
  <p>I don't have a template made for this button, obviously.</p>
  
  <p>I am loading my ResourceDictionaries dynamically in the code behind.</p>
