Hiho,

like the title says: IE 7 wont display page if in iframe and Your plugin is active. To be exact it will show the Page as long as you wont press the Ok Button on the Cannot Open Page Dialogbox.
Reason: Script inside body element in an iframe throws that error.

Fix:
$scripttxt as class var

in constructor

add_action('wp_footer', array($this, '__footer'));

in class

function __footer()
	{
		echo $this->scripttxt;
	}

and in function __displayDynamicMap
put all strings from '<script type="text/.... onwards till return in a temp var and set new classvar before return
$this->scripttxt = $scripttxt;

changed content.php

<?php
class bingMapsForWordpressContent
{

.
.
.
	/**
	 * Script which gets put in the Footer
	 * @var string
	 * @access public
	 */
	var $scripttxt = "";
