WPF window against of taskbar
===

I have a problem with my WPF window. I set the `TopMost="True"` to be forever on top. The problem is that when I click on another window (for example Firefox) my window remains on top, but in back of taskbar (Start bar), so the taskbar is in top, then my window, and then the Firefox window. I use Windows 7.

**Quesion: what I must to change in my code to set my window against of taskbar?**

XAML code:

    <Window x:Class="WpfApplication1.MainWindow"
            xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
            xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
            Title="Pixeli morti" Height="350" Width="525" WindowStyle="None" WindowStartupLocation="CenterScreen" WindowState="Maximized" ResizeMode="NoResize" Background="#00000000" Topmost="True" AllowsTransparency="True">
        <Grid>
            <Canvas Name="canvas1" />
        </Grid>
    </Window>

Thank you in advance. Wait for your replies.
