What if the user is browsing with Opera or Firefox? Don't you want to know
whether the web page is the topmost in those cases as well? Or do you only
need to know it if the user is browsing with MSIE?

Other than that, figuring out which window is the active topmost on a
user's computer can probably be figured out using window.onfocus() or
document.onfocus().

Haven't tested this:

<html>
<body onfocus="alert('Hello, world!')">
<p>Hello, world!</p>
</body>
</html>

then when switching between different browser windows with the same page,
each page should alert.

Then please enlighten us and explain how the question can be interpreted
differently?
