Iframe covers navigation bar, needs close, open to fix?

I have a small webpage with a form, iframe-d in. When I put invalid input inside the form, the iframe covers up the navigation bar and I can't开发者_如何学JAVA get the navigation bar back without closing and opening the page again.

Here is where I am (temporarily) hosting the webpage: dl.dropbox.com/u/1144456/rlp/v2/demo.html

the css stylesheet: dl.dropbox.com/u/1144456/rlp/v2/contact-us.htm

To recreate this problem, click the last tab and just click submit.

Your form is submitting into a target element. Remove this, allowing it to self-target, and it works fine. In the form page, change:

<form action="#public" ...>

to

<form action="" ...>
