I am creating a program for taking screenshots of a game, out of the game. When I press the hotkey it works, but with the open game in fullscreen it does not detect the key.

My code:

```
protected override void WndProc(ref Message m)
{
    const int WM_HOTKEY = 0x0312;

    switch (m.Msg)
    {
        case WM_HOTKEY:
        {
            if ((short)m.WParam == 1)
            {
                start = DateTime.Now;
                progressBar1.Maximum = 1;
                progressBar1.Step = 1;
                progressBar1.Value = 0;

                DoRequest();
            }
            break;
        }

        default:
        {
            base.WndProc(ref m);
            break;
        }
    }
}

```

I register the global key using:

```
RegisterHotKey(this.Handle, 1, (int)KeyModifier.None, Keys.F11);

```

Help-me :/
