I am having an issue with code provided by Listingbook.com:
<script id="lb_client_form" type="text/javascript" src="http://www.listingbook.com/cgi-bin/controls/client_form/?uid=A68659&btn=green.gif"></script>
I've added this to the page html. The button shows up fine, but when you click on it the popup appears and it looks as if the menu and sidebar are showing through the popup.

I've read that this may have somethng to do with "overflow" but I'm not sure which overflow to adjust.
I've been searching for a solution for hours.. I am a WP noobie, I have a feeling this is a pretty easy fix but I don't want to "fix" the wrong thing!
