I'm working on a site and have come across a strange problem. I wasn't sure where to post this, so forgive me if its in the wrong section. I have four links across the top of my page, in Firefox the first 3 are clickable, but the 4th is not. In IE all 4 are clickable.

Here is the code for the 4 links
Code:
<div id="nav">
<div class="navContainer">
<a href="./index.html" class="navActive">Home</a>
<a href="./profile.php" class="navLinks">Profiles</a>
<a href="./archives.html" class="navLinks">Archives</a>
<a href="./gallery.php" class="navLinks">Gallery</a>
</div>
</div>
