WP 3.5 Media Uploader

Not sure if this is just something I did wrong with the code or if anyone else also had a similar issue with the uploader.

In my custom meta box class i use the new uploader and everything works 100% in the posts, page and custom post type pages.

However when I included the new uploader into my settings api class, each time I click the upload button 2 instances of the uploader is opened?

I tried tracing the uploader events and tracing the button events but cannot see what i have done wrong here?

Any help would be greatly appreciated.

PS. :
Server: IIS 7
PHP Version: 5.4.0
No plugins active or installed

Code for upload button:

case 'upload':
	echo '<input class="' . $field_class . '" type="text" id="' . $id . '" name="tsrespo_options[' . $id . ']" value="' . esc_attr( $options[$id] ) . '" />';

    echo '<input id="' . $id . '_upload_button" class="button" type="button" value="Upload Image" />';

    echo '<script type="text/javascript">
		    jQuery(document).ready(function($){
                $("#' . $id . '_upload_button").click(function(e) {
                    var frame = wp.media({
                        title: "Choose Image",
                        multiple: false,
                        library: { type: "image" },
                        button: { text: "Ok" }
                    });
                    frame.on("select", function() {
                        var attachment = frame.state().get("selection").first().toJSON();
                        $("#' . $id . '").val(attachment.url);
                    });
                    frame.open();
                });
            });
        </script>';

	if ( $desc != '' )
		echo '<br /><span class="description">' . $desc . '</span>';

	break;
