We can listen for this event and try to cancel further execution (https://developer.mozilla.org/en/DOM/event.preventDefault). So something like: document.getElementById('content').contentWindow.addEventListener('DOMWillOpenModalDialog', function(e){ e.preventDefault(); }, true); Good luck! Tom Hi Mike,
