Bingo ! Lee - that link referred to two attributes document.body.scrollWidth 
and document.body.scrollHeight which I think are IE specific.

Now the production code has: 

function resize() {
        if (document.layers) {
                window.innerHeight = document.height + 20;
                window.innerWidth = document.width;
                if (window.innerHeight > screen.availHeight - 30) {
                window.innerHeight = screen.availHeight - 30;
                // Allow for width of scrollbar
                window.innerWidth = document.width + 20;
                }
        } else {
                if (document.body.scrollWidth) {
                        w_width = document.body.scrollWidth + 30;
                        h_height = document.body.scrollHeight + 35;
                }
                self.resizeTo(w_width, h_height);
        }
}

These are slightly strange attributes, in that document.body.scrollHeight 
varies with the original height of the window, even for identical content. 
This may well be related to what Adam was talking about with an initial 
resize for IE. But in any event, I know have a solution which is pretty good 
for most browsers out there.
