WP Admin Different Amimal?

Seems like everything that works on the front end, does not in the wp admin area.... I am using a plugin called easy fancy box. I can display inline content fine on post and pages using this code

<div style="display:none" class="fancybox-hidden"><div id="fancyboxID-1">
...inline content here...
</div></div>
<a href="#fancyboxID-1">Read my inline content</a>

but am not able to get that working in the wp-admin area....

Anybody know of a quick hack
