Why is my CSS drop-down menu opening behind a DIV in IE7?

Question

This issue has been stumping me.

This only happens in IE7. I saw some similar subjects, and tried the solutions, but couldn\'t get them to work.

Any ideas?

Answer 1

Try this:

#nav_main ul
{
  overflow: auto;
}

#nav_main ul li
{
  z-index: 10;
}

Another problem could be that the Flash video is doing it, but since I don't use Flash, I can't help much.
