Problem using menu registered with GM_registerMenuCommand

[QAZ]

Hi,

I'm trying to create content on the fly and on demand, by registering
a callback using GM_registerMenuCommand. However, I'm not able to
consistently see the result of that callback. For example:

// ==UserScript==
// @name Test Greasemonkey on Amazon
// @description Test Greasemonkey on Amazon
// @include http://www.amazon.com/*
// ==/UserScript

// Register this cool app
function registerUserMenu() {
GM_registerMenuCommand('Test', showTest);
}

function showTest() {
var element, cell;
element = document.createElement("div");
cell = document.createTextNode((new Date()).toLocaleString());
element.appendChild(cell);

var body = document.getElementsByTagName("body")[0];
body.appendChild(element);

GM_log("Inserted");
}

//showTest();
window.addEventListener("load", registerUserMenu, false);
// ---------- ---------- ---------- ----------

When going to the test web site (amazon.com for example, then the
Kindle page), often times when I click on the user script menu item, I
can see the test message is logged into the error console, but the
test div has not been added to the page content. If I refresh the
current page, the test menu would always work. What gives?

I'm using the latest GM addon with FF 2.0 and 3.0b5.

Thanks.

First, this event listener is pointless. Just call gm register menu
command.

Second this:

> var body = document.getElementsByTagName("body")[0];
> body.appendChild(element);

Would be much more straightforward as "document.body.appendChild(element);"

That said, Amazon is doing something strange. If I run the same script
on www.example.com, it works fine. That's all I've got right now.
