Like button issues on IE 8

Anyone else having issues with this in IE 8?

It works perfectly for me in Firefox, Safari (Windows), Opera and Chrome. But with IE 8, I just get a pop-up from [You must be registered and logged in to see this link.] when I click the "Like" button. When I go to FB, the URL I attempted to like is not liked.

I am adding a function to track "likes" when FB.Event.subscribe fires; this works perfectly in the aforementioned browsers, but I cannot get anything — my tracking code, the debugger or an alert — to fire from inside the FB.Event.subscribe function in IE. I just get the pop-up...

Any ideas? Thanks in advance for your time.

What popup you said you get on IE?

It's just a blank page w/ the Facebook header.

Here's my code (the alert is never reached):

window.fbAsyncInit = function() {
FB.init({ appId: '[my_app_id]', status: true, cookie: true, xfbml: true });
FB.Event.subscribe('edge.create', function(href, widget) {
alert('if you can see this, you must not be using IE...');

/* "LIKE" TRACKING CODE HERE... */
});
};

Some additional info...

1) I am clearly logged into Facebook and my page with the like button seems to "know" this, so I am assuming that FB.init is working correctly.

2) If I like my page in another browser and then load that page in IE, it shows, "one person likes this" but doesn't seem to know that I am the one who likes it; in the other browsers, it knows I like it.

3) I did find this: [You must be registered and logged in to see this link.] I am developing in ASP.NET, and my test page URL does have a port number in it. I'm going to plan on deploying my test page and trying it there...

Thanks,
Rob

Blerg...

OK, the fix for this is to use NEITHER localhost:[port] NOR just localhost but DO use 127.0.0.1 instead. Then, it works like a dream in IE8 (including compatibility mode)...

What. A. Pain.
