Determining position of the browser window in JavaScript? -

For various silly reasons, I want to be able to detect the rectangle of the browser window on the screen. Title bar and all.

Is it possible, or is javascript limited to the view port of your page?

Edit: Maybe I'm unclear, but see Port is part of the page that appears in the window. This can not be the word used commonly with the browser, but it is normal in graphics.

For standard browsers:

X - Y -

X for IE -
Y -

Keep in mind, beware of multi-monitor setups ...
