In IE7 (at least) the resize event handler is called twice.

For example, in the following script I get 6 alerts instead of 3.

The commented code is a workaround.

jQuery( window )
.bind( 'resize', /*{ count: 1 },*/ function( event ){
/*	  
  if (event.data.count == 1)
  {
    event.data.count = 0;
  }
  else 
  {
    event.data.count = 1;
    return;
  }
*/	  
  var w = $( window );
  var d = $( document );
  var b = $( 'body' );
  alert( 'w: ' + w.width() + ', ' + w.height() );
  alert( 'd: ' + d.width() + ', ' + d.height() );
  alert( 'b: ' + b.width() + ', ' + b.height() );
} );

I thought that the 'one' method could fit here but maybe I misunderstood its intended usage. In fact, it works once, and then never more. For the first resizing, the handler bound with 'one' is called, but for any other resizing after the first one, the handler is never called again. (unbound?)
