Copyright display errors in embedding a Google Map when veiwed with IE

Hello. I have an issue with embedding a Google map when viewed in IE. I am not using WPMUDev's Google Maps plugin. I am instead manually embedding the map. I have uploaded a screenshot of what the problem is. I suspect it's some kind of CSS or javascript error, but I am using the WordPress Twenty Twelve theme for testing. I am using a custom plugin to display the map other than that there are no additional plugins. Also, this often does not occur when first viewed in IE, but usually on refresh, or is a user clicks the back button and returns to the page. This only occurs on IE so debugging it using something like Firebug is difficult. Any help or alternatives would be greatly appreciated. Thanks.
