//DD Tab Menu- Script rewritten April 27th, 07: http://www.dynamicdrive.com
//**Updated Feb 23rd, 08): Adds ability for menu to revert back to default selected tab when mouse moves out of menu

//Only 2 configuration variables below:

var ddtabmenu={
	disabletablinks: false, //Disable hyperlinks in 1st level tabs with sub contents (true or false)?
	snap2original: [true, 300], //Should tab revert back to default selected when mouse moves out of menu? ([true/false, delay_millisec]

	currentpageurl: window.location.href.replace("http://"+window.location.hostname, "").replace(/^\//, ""), //get current page url (minus hostname, ie: http://www.dynamicdrive.com/)
