I am posting this because i found an solution here that helped me with a mind-numbing problem and I want to share it.
I frequently come across an issue where I have a nav menu at the top of the page with a flash banner/image below it. The nav menu and flash overlap on the z-index and I cannot access the drop-down menu behind the Flash element.
To fix:
- Flash element needs { z-index:0px; } and <param name="wmode" value="transparent" />
