Hello,

I am developing a website and i was trying to set up a superfish menu.
1. The link on my <li class="sub-menu"> does not work on the first left click of the mouse, it opens on the second click though.
2. Links related to sub-menu items do not work at all, if I click once they do not open, if I click a second time, the link related to my <li class="sub-menu> opens.

This is my superfish.js

Code JavaScript:
@import url([url]http://fonts.googleapis.com/css?family=Anton);[/url]
nav{position:relative;margin:27px 10px 1px 10px;
}.sf-menu ul{
position:absolute;top:-999px;

Code HTML4Strict:
And this is the piece of HTML
 
                <ul class="sf-menu">
                    <li class="current"><strong></strong><a href="index.html"><strong></strong>Home</a>
                    </li>
                    <li class="sub-menu"><strong></strong><a href="about.html"><strong></strong>About</a>
                        <ul>
                            <li><a href="#">history</a></li>
                            <li><a href="contacts.html">contatti</a>
                        </ul>
                    </li>
                    <li><strong></strong><a href="products.html"><strong></strong>Products</a></li>
                    <li><strong></strong><a href="index2.html"><strong></strong>Services</a></li>
                    <li><strong></strong><a href="#.html"><strong></strong>Store</a></li>
</ul>
                        <div class="clear"></div>
            </nav>

Can you help me fix this issue please?
