title: How to disable scrollbars with JavaScript?
body: <p>I need to lock the browser scrollbars when I show a div that represent a modal window in Internet Explorer 7 only.
  Googling I found that I can use <code>document.body.style.overflow='hidden'</code> but this doesn't work for IE7. I also tried with <code>document.body.scroll="no"</code> which works but only after I mouse over the scrollbar :-S</p>
  
  <p>Does anybody knows a better aproach?</p>
