How to delay the loading of expose Created Feb 12, 2010

I have a div on which I use expose.
Here is the simple code:

$("#banner-box").mouseenter(function() { 
            $(this).expose({
            	maskId: 'mask',
                api: true
             }).load(); 
        });

The problem is that for users who go over very quickly over the box in the screen, it's disturbing. I would like the expose to be loaded only after the mouse is hover the box for say 1000ms. Only then, I would like to trigger the expose. So when somebody goes over quickly, nothing happens.
I was unable to find a solution for this...
Can someone help?
