// IE/WIN <SELECT> Z-INDEX HACK - Craig Morey
// You'll love this one. IE/Win sets the z-index of <select> inputs as higher than anything.
// That means that navigation menus that appear with the z-index of 1000 (for example)
// are obscured by <select> items that should be beneath them. Bonkers. Madness.
// This solution actually hides the select boxes when the menus are activated, 
// but the boxes don't seem to disappear because there's a background image of the select boxes
// it's a crappy solution to a shitty problem, but with JS and CSS hacks, it only runs for IE/Win
