What do you want to scroll? If it's the whole page you should get rid of
the frames altogether.
Setting the inner frameset to noscroll will just do exactly that - not
allow any scrollbars to appear for the inner frameset. If the inner
frameset is in another frame that allows scrolling, then yes, you'll get
a scrollbar. But then I would recommend nesting a regular HTML page
instead of a nested frameset.
