Improving jQuery UI ajax loading dialog for all page loads

My web development project loads a lot of content via JSON and AJAX (aren't these basically the same thing).

I have implemented a loading gif pop up in a jquery UI dialog. This is hooked up to the .ajaxStart and .ajaxStop events. 

$(document).ready(
        function () {
            $(window).load(function () { Load(); });
....

 function Load() {
.ajaxStart(function () {
//Show popup
}
.ajaxStop(function () {
//Hide popup

}

So this is pretty good, and whenever i'm loading content via ajax the loading pop up appears. Great. My next question is - the feedback im getting - they think its weird that there is loading for this content, but then when you request an entire new page in the web app, the 'load' takes a while, and there is no loading dialog like the other ajax loading examples. Personally to me - this makes perfect sense, but the user doesn't like it.

Is there any easy way I can hook up my same dialog to page loads? I'm thinking if there is a way to know/jquery event for when they request a new page, I can just pop the loading dialog up and leave it there till the new page has loaded.

Grateful any advice?

Thanks.

You can't leave the loading dialog until the next page loads because there's often a pretty large gap between the unload of the current document and the loading of the next.

If your site was completely ajax then you could do it, but making a site completely ajax driven takes keen attention to detail (back button support, bookmarking, events, etc), so I'd think twice about going down that path.

Sure, check out the unload event. http://api.jquery.com/unload/

So literally just chuck 

$(window).unload(function () { Load(); });

In your document ready and it'll show the popup when the user navigates to a new page (might need to customise it because you don't need any ajax request considering you're not loading any data dynamically).
