You can write a delay method, such as this
  #region delay (in seconds)
        public void Delay (int delayTime)
        {
            DateTime now = DateTime.Now;
            int s;
            do
            {
                TimeSpan spand = DateTime.Now-now;
                s = spand.Seconds;
                Application.DoEvents ();
            }
            while (s <delayTime);
        }
        #endregion
This will not wait like a crash during the delay
