I believe this bug was supposed to have been fixed in the move from jQuery Calendar to ui.datepicker, but I'm still seeing sporadic "Operation Aborted" errors in Internet Explorer, both 6 and 7, when the datepicker is initialized. Frustrating problem because it's very intermittent.
The code I'm using is pretty simple; in the HTML: <input type="text" size="1" id="calendarDaily" value="" readonly="readonly" /> Then in the $(document).ready function, I instantiate the datepicker with this: $('#calendarDaily').datepicker({ showOn: 'button', speed: 'fast', buttonImageOnly: true, buttonImage: '/dailyarchives.jpg', buttonText: 'Calendar', minDate: new Date(2001, 2 - 1, 7), dateFormat: 'YMD-', onSelect: function(thedate) { eval("parent.location='/index.php?date=" + thedate + "'"); } }); Works fine in all flavors of Mozilla/Firefox, and in Safari -- IE is the only problem.
