So, our school's robotics team was playing around with a Drupal based site, and we are modifying the multiflex theme to suit our needs. The problem is that we give .header-middle a height of less than 150px, (changing the background image, of course), "dead zones" appear on the nav2 menubar. By this I mean that mousing over certain parts of the menubar, the menu isn't highlighted, and there is no hyperlink. These dead zones always appear in the upper-right corners of the menubar. .header-top has a height of 150px, if that makes a difference. Please help, this is very frustrating.
