Hi, I am having some problems with this modified version of Lightbox. I had a programmer implement this into the site and then one day it just stopped working. I'm trying to fix it myself, with no success.

To view the problem go to: http://www.uscgq.com/question/deck/2 and click the red flag icon.

The lightbox opens, but only shows the "Loading" message.

I have isolated the problem to somewhere in the Lightbox.js just don't know where or what it is. Any help is greatly appreciated!

Hi

Firefox reports activeX objects undefined ----- after that the page loads ok.

The rest is beyond my level i'm afraid.


var Ajax = {
550 getTransport: function() {
551 return Try.these(
552 function() {return new ActiveXObject('Msxml2.XMLHTTP')},
553 function() {return new ActiveXObject('Microsoft.XMLHTTP')},554 function() {return new XMLHttpRequest()}
555 ) || false;
556 },
