[SOLVED] .swf in header widget area not displaying in correct order

I used the Add New Widget area to add a .swf to show on top of my header. It looks great except when it sits on top of the background overlay for my NexGEN Gallery images. I have tried to fix this with z-index but I either have the wrong CSS or it is not a z-index problem.

The problem can be seen for example when you click on the pictures in this page: http://www.daisytwist.com/bounce-houses/

Once the picture is open, you will need to scroll to the top of the page to see the .swf in the header on top of the background overlay.

Any ideas?
