How can I add scrollbar to the frame. I am using contribute 4.1. I have a page
with four frames. Only main frame has scrollbar, others have not, although they
have content that is bigger than displayed content.

Example: In my left frame is a menu. When I use a laptot with 15" display and
surf to my web page, I can not see the whole menu and can't scroll down with my
mouse wheel. I would like to add vertical scrollbar.

Help in advance.
