I agree, absolute pixel values are not really any good to specifying the
size in any environment that should run on more than one machine.
However, how are you supposed to control the size of your dialog otherwise?
A normal web page is resized to fit into the window, and not vice versa,
because the user usually has the browser open before he navigates to a
page and constant resizing of the browser window would be irritiating to
put it mildly.
But this is not the case with popup/dialog windows. (At least the cases
where they are not abused brutally)
There is no reasoneable "default size" the page could adjust to. If the
author can't specify the size of a popup/dialog, what algorithm should
the UA use to find out the correct optimal size?
As an example, many rich text editors use modal dialogs to specify font
settings, etc. The HTML in the dialogs could be displayed in a
normal-sized browser window effortlessy. However, it would look pretty
