i have an asp.net mvc site and here is a dynamic tooltip using qTip

Here is my code:

$('a.showNutritionInfo').each(function() {

    $(this).qtip({
        content: {
        text: '<img src="../../images/ajax-loader1.gif" alt="" />',
        style: { width: 450 },
        url: '/Tracker/NutritionInfo/' + $(this).attr('id'),
        method: 'get'
        }
    });
});

this works perfectly EXCEPT the width attribute listed above is ignored. No matter what i put in that width attribute, i get the same size width tooltip which is about half of the width that i need. the height is perfectly fine.

any ideas? is this a bug in the product ?
