I've got the most simple application ever: single window with one single toggle button:

<Window x:Class="WpfApplication1.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        Title="MainWindow" Height="350" Width="525">
    <Grid>
        <ToggleButton Content="This is my ToggleButton" />
    </Grid>
</Window>

When I now click on the toggle button, really nothing happens. When I setup event handler for Checked and Unchecked event, and then click the button, first the Checked and then Unchecked get fired. So the button seems to work correctly ...

I am compiling to .NET 4.5 and I am using Windows 8 RTM.

Is this behaviour related to the Windows 8 style of displaying buttons (no "3D" border)? Can anyone confirm?

UPDATE 1 I made up an image to show what I meant:

Windows 8 vs Windows 7 toggle button

As you see, in Windows 8 "nothing happens" when clicking on the toggle button, it simply does not get "toggled". This seems to be a bug, related to the windows 8 style of displaying buttons ...

Unfortunately it doesn't fix the problem for me :(
