title: GNU Screen refresh problem
body: <p>I've recently started using GNU Screen but have run into a very annoying problem. </p>
  
  <p>In any screen window if I press the left arrow key or backspace when there is nothing typed at the prompt the screen seems to refresh, causing a slight flicker. After typing some text at the prompt using the backspace or left arrow won't cause the flicker (at least until the first character in the prompt is reached).</p>
  
  <p>Anyone seen this before?</p>
