WPF menu mouse over issue

HI,

I have menu which automatically takes default border when I do Mouse over. I don't want that gray border on mouse over. How would I do that?

Here is code:

<Grid>    

      <Menu Background="Wheat" Margin="0" Width="110" x:Name="TextMenu1" BorderThickness="0">
            <StackPanel Orientation="Horizontal" Margin="0" HorizontalAlignment="Stretch"  Width="110">
                <Image Source="../../Resources/Images/placeholder_textObject.png"  Stretch="Uniform" Width="36"         Height="36" VerticalAlignment="Center"/>
                <TextBlock Text="Text"  HorizontalAlignment="Left" VerticalAlignment="Center" Margin="5,0,0,0"></TextBlock>
            </StackPanel>
        </Menu>

</Grid>

Thanks

Dee
