// Created: 9/23/2006
// Purpose: 
//      Several scripts that need to be included in every page
//      One is to make the drop down menus work in IE6
//      The rest are for the High Contrast stylesheet
// 
//
// Modified:
// 
//  5/21/07 - FK - Added Flash JS
//
//  5/21/07 - PL - Added three facdat versions.
