Scrolling stack windows?

[John Tregea]

Hello again fellow Revolutionaries : )

I have built an interface where users can keep on adding new layers of
information down a stack window by clicking a button at the bottom of the
bottom most layer (the button clones the last group and re-populates the
fields to suit the new context).

Because the users frequently want to display 6 or 7 layers one below the
other they quickly run out of screen space.

I believe there are no scrollbars that I can turn on in the stack window
like I can on a text field? I hope I am wrong? But if I am correct can
anyone point me to examples of scrollbars being used to scroll multiple
groups within a window?
