//
// permits multiple widgets to register their own onLoad and onUnload handlers
//
// The developer can have his own custom functions automatically execute
// during page load and page unload by using the following functions.
// add_on_load(function_name)
// add_on_unload(function_name)
//
// requires submit_ifpp_form to define
// unshift(), push(), pop(), and concat()
//
//

//removed becoz the first item is sometimes
//off the bottom of the browser, causing it to scroll down.
var on_load_stack = ["set_focus_on_first_item"];

//var on_load_stack = [];
var on_unload_stack = [];
