private void notifyIcon_MouseDoubleClick(object sender, MouseEventArgs e) {

        ShowInTaskbar = true;
        notifyIcon1.Visible = false;
        WindowState = FormWindowState.Normal;
    }

Answer 1

You are not showing the form in the NotifyIcon double click event.

Change your code to -

private void notifyIcon_MouseDoubleClick(object sender, MouseEventArgs e)
        {

        Show(); //display the form
        this.WindowState = FormWindowState.Normal;
        notifyIcon1.Visible = false;
    }

Also, look at the Remarks section of the ShowBalloonTip method
