Scrollbars not appearing in new window

Question

I'm trying to open a new window, and for some reason the scrollbars will not appear in Firefox or IE, but do work fine in Chrome & Opera.

here's the javascript code on the button (from a PHP script), and below, if it's more readable, the HTML that is output:

window.open('".BASE_URL."utils/viewProfile.php?key=".$key."',null,'width=1280,height=1024,toolbar=0,location=0,directories=0,status=0,menubar=0,scrollbar=1,resizable=1')"

<input class="input-button btn_generic_nav6up" type="button" onclick="window.open('https://domain.com/utils/viewProfile.php?key=8UjKKydCyTx1V7E2A0xklA%3D%3D',null,'width=1280,height=1024,toolbar=0,location=0,directories=0,status=0,menubar=0,scrollbar=1,resizable=1')" value="view profile" />

Answer 1

in the window, add this to the stylesheet:

html, body{
  overflow: scroll;
}

Answer 2

Off the top of my head, I think it's 'scrollbars' (plural) and not 'scrollbar'.

Also I thought it was 'scrollbars=yes' rather than 'scrollbars=1', but it's possible either will work.
