Z-index issue on dropdowns

I could’ve sworn I had this working perfectly when I launched the site, but for whatever reason the dropdowns are hiding behind the rotating banner in Chrome and IE8.


I went back through and I think I’ve got my stylesheet z-indexes in order so any suggestions would be much appreciated.

Seems to be just a problem in IE7 to me. Anyhow, you could try something like this:

.page_block {
  position: relative;
