Issue With Drop-Down Menu

Ok, I’m having a bit of an issue with some drop-down menus.
The link I gave is typical of several pages on my site.
What I have is image galleries set up on my posts but the drop-down menu is displaying behind any captions of the images the menu drops down over. Changing the theme fixes the problem.

I’ve tried to edit the Z-index of both the drop-down menu and the image captions but I’m not having any success. It’s quite possible I could be doing it wrong so any help would be appreciated.
