If you look at the following website:
[login to view URL]
click on the sign up link in the upper right. You will notice that there is a modal box drop down, this is working correctly in both FF and IE.
Now sign up for the site and go to the users area, when you click to add a new listing (under my listings) you can see that the same modal box no longer works correctly in IE, though it works fine in FF.
My first thought was a CSS error though this does not make sense since it works on the main site, just not in the users area.
Your task is to identify the error and correct it.
