Dark Shaddows on Internet Explorer :-)

We built a drupal site with google maps, and it worked fine on our browsers. However, our customer pointed for us on a big & scarry shaddow where the markers should have seen

Aperently he was using ie7, and we found a javascript error in the markers. Doing some research and changes, we returned to the default settings, and suddenly it worked fine.

The problem was in a file we made with a unique markers without shaddow, that included the shadow attribute with a null value ;

</code></p>
<p><code> Defaults [defaults] shadow = "" anchorX = 4 ...</code></p>
<p><code>

this breakes the IE and got us a javascript error.

so, what we had to do is to rem/delete it using  ;

</code></p>
<p><code>Defaults [defaults] ;shadow = "" anchorX = 4 ... </code> </p>
<p><code>

and use a marker with shaddow
