test.user.js

// the real version of this file is named test.user.js and it does at least
// load into GM even if it doesn't work

// When I run this script on the page below
// @include http://test.barrycarter.info/select1.html
// I want it to alert "foo" everytime I change selections.
// Instead, I get "Error: Component is not available"

// NOTE: works fine in firebug

// generic test greasemonkey script
