Featured Content Slider overlapping drop down menu on Joomla site - quick fix?

[efflux]

1) Script Title: Featured Content Slider

2) Script URL (on DD): http://www.dynamicdrive.com/dynamici...tentslider.htm

3) Describe problem:

Just put the featured content slider on the homepage of a new site I'm building with Joomla. The problem is that the slider overlaps the drop down menu of the navigation only after the 10th rotation.

Here is a link to the demo site.

(I increased the speed of the slider so you don't have to wait long to see the issue) Just scroll over services, and wait until the 10th rotation of the slider.

Strange eh?

I tried bumping up the z-index of the menu items, but still happens only after the 10th rotation. IE seems to be fine, but firefox, safari, and chrome all have the issue.

Any help would be much appreciated!

Here is a link to the menu's css:

I fixed it.

All I needed to do was add a low z-index value for the class ".sliderwrapper" By default, it didn't have any z-index value assigned to at all.

Still don't know why the bug occurred only after the 10th rotation though.
