JQuery, Ajax and Internet Explorer - callback only works when response is blank
<p>My code works perfectly in FF, Safari and Chrome... just in IE 7 and 8 this happens...</p>

<p>My JQuery AJAX post looks like this:</p>

<pre><code>$.post( 'page.php', { test: 'testing' }, function(r){
    alert('Data: ' + r);
});
</code></pre>

<p>Now, in IE, if the response (r) comes back blank, it will display the alert. However, if there is anything returned in the r (even if it's just a digit such a 1), it doesn't show the alert. No errors come up, it just doesn't show the callback...</p>

<p>Any ideas what might be wrong?</p>
