Since I started using PIE everything worked amazing, but I found something odd in a header:

<div id="page-header-content"> //This DIV has a background image
<h1><?php the_title(); ?></h1>
<nav id="content-options"> //This nav has a green background color and rounded corners
<ul>
<li class="opt-share">Option 1</li>
<li class="opt-print">Option 2</li>
<li class="opt-price">Option 3</li>
</ul>
</nav>
</div>

The thing is, that after PIE reads the rounded corners and applies them, it hides the NAV green background behind the background image of the upper DIV, but the <ul> options stay on top :S

Any idea why this happens or what can I do about it? Forcing z-index = 1 or 1000 doesn't do anything.

there goes my record of not being one of those people that asks before searching the FAQ

Thanks a lot!
