top-bar top-link-section issue

Hi,

I'm using the top-bar as seen on this page: http://themes.semicolonweb.com/html/canvas/index-magazine-2.php
When you hover on the "Login" item, the top-link-section with the input fields appear.
The problem I'm facing is that when I double click on one of the input text fields to select a pre-filled value, the popup disappears.
Same kind of issue when you leave both fields blank and hit the "Sign In" button, the "Please Fill Out This Field" message appear but if I hover on it, then the top-link-section disappears.
Is there any way to fix that?

Thanks!
