CSS Dropdown Menu being over-lapped by other other screen elements

[adz1809]

I have a CSS Dropdown Menu being over-lapped by other other screen elements. I've looked at z-index, but this seems to be having little effect.

Any ideas welcome.

cheers

I am unavailable all week but try using position relative on the drop down or the other elements. Forgot how to do this. It's an IE bug.
