title: I can't clear the SELECT list with "selectedIndex = -1" in Internet Explorer 8
body: <p>after an hour of trying to find a solution, I give up (temporarily). "this.selectedIndex = -1" clears all select element just fine in FF and other browsers, but NOT in Internet Explorer 8. </p>
  
  <p>any idea how to clear select elements in IE?</p>
  
  <p>thanks!</p>
