I've just noticed that on my site when you click the facebook like button and the little windows opens for you to post a comment, that window appears behind my drop down menu.

I have a z-index of 1000 on the dropmenu so thats why it appears in front but I'm buggered if I can figure out which div id or class to put a higher z-index on which will make it work. I've tried all types of combos but haven't stumbled across the correct answer yet. I'm not so strong with css

Any wizards out there know the answer?
