Netscape & JavaScript

I want to use JavaScript to open a new window. No toolbar, menubar, status, etc. But I want to be able to scroll. I tried window.open(url, “my_window”, “toolbar=no,menubar=no,location=no,scrollbar=yes”); but I still don’t get the scrolling. Users must be able to see all the text, they have to be able to scroll.

The code must work with all versions of Netscape 4, on all platforms.
