Submenu disappears behind Flash Slider

I have a Flash Slider with this code:

<div id=“flashcontent”><strong>You need to upgrade your Flash Player.</strong></div>
<script type=“text/javascript”>
var so = new SWFObject(“preview.swf?keepSelected=t&selectedWindow=0&imageWidth=512&imageHeight=380&sWidth=940&sHeight=380”, “940”, “380”, “8”, “#ffffff”);
so.addParam(“allowFullScreen”, “true”);
so.addParam(“wmode”, “transparent”);

The submenu above this slider gets hidden behind the slider. I’ve already tried ‘position: relative’ without success. I understand that entering "param name=“wmode” value=“transparent” would solve the issue, but it doesn’t seem to be working in IE, Chrome, or Safari.

With IE7 the submenu goes behind the slider, but with IE8 and above the submenu seems to be okay.
It seems to work fine in my current Chrome too.

It would be good to gain further clarification about the situations in which the problem is occurring.

It seems that the submenu was hiding behind the banner. I wound up redoing it and seems to be working well now on most browsers.
