IE doesn't submit form via AJAX when enter pressed

This problem is easily solved, and whenever I get a chance to remember how to do CVS again and sit down and resubmit some fixes, I'll include it.

Add the following to the end of chatblock.js

// check to make sure JS is enabled and functional
if (Drupal.jsEnabled) {

  // add our stuff inside the header of the table
  $(document).ready(function() {
    $('#edit-chatblocktext').focus(function () {
	  // add a keydown event on focus
      $(this).keydown(function (event) {
        // get the event which is browser dependent
        var e = event.which || event.keyCode;
          
        if (e == 13) {
		  var el = document.getElementById('edit-chatblocksubmit');
		  chatblockSend(el);
		  return false;
		}
		else {
		  return true;
		}
	  });
	});
	
    $('#edit-chatblocktext').blur(function () {
	  // get rid of the keydown when we don't need it anymore
	  $(this).unbind('keydown');  
	});
  });
}
