//  ALTTXT V1.2
//  BY: BRIAN GOSSELIN OF SCRIPTASYLUM.COM
//  ADDED FADING EFFECT FOR IE4+ AND NS6+ ONLY AND OPTIMIZED THE CODE A BIT.
//  SCRIPT FEATURED ON DYNAMIC DRIVE (http://www.dynamicdrive.com)
//  Modifed by DD for doctype bug on Nov 13th, 2003

var centertext=false; // CENTERS THE TEXT INSIDE THE BOX. YOU CAN'T SIMPLY DO THIS VIA STYLE BECAUSE OF NS4.
