Switching problem to window mode ALT + ENTER

[GoogleCodeExporter]

I run the September 2011 SDK. 
I'm using the tutorials on your page and I changed IsWindowed in the 
SwapChainDescription to false that the application starts in fullscreen mode.
When I switch to non-full-screen with ALT + ENTER, all I see is a blank box 
that is not moveable.
When I start the application in windowed mode I can go to fullscreen and back 
to windowed mode without a problem. 

After all, I tried following solution:
    renderForm.KeyDown += (o, e) =>
            {
                if (e.Alt && e.KeyCode == Keys.Enter)
                {                 

                    bool isFull;
                    Output temp;
                    swapChain.GetFullScreenState(out isFull, out temp);
                    isFull = !isFull;
                    swapChain.IsFullScreen = isFull;
}
}

But this doesn't work too for me. How can I fix this problem in the tutorials? 
Thank you.

I think this is an issue with the way Winforms interacts with DXGI. If you call 
Form.Show() before creating the fullscreen swapchain, everything works fine. If 
you don't call it, when you switch back to windowed mode you get that weird 
blank window effect.
