How long a pause do you need?

Sleep() makes your app completely UNRESPONSIVE during the sleep interval...your app won't respond to your users events and won't repaint itself correctly.  This may be unacceptable depending on your application and the length of the delay needed...

You could use a Timer control, or possibly use a polling loop:

        Delay(5); // five second delay

        private void Delay(int DelayInSeconds)
            TimeSpan ts;
            DateTime dt = DateTime.Now.AddSeconds(DelayInSeconds);
                ts = dt.Subtract(DateTime.Now);
                Application.DoEvents(); // keep app responsive
                System.Threading.Thread.Sleep(50); // Reduce CPU usage (keep interval SMALL)
            while (ts.TotalMilliseconds > 0);
