TF's visual mode uses "scrolling regions" to allow the upper output region to scroll without affecting the lower input region. However, this interferes with the scrollback mechanisms of some terminals, including OSX Terminal.app. I am not aware of any workaround for TF 4 and Terminal.app.
TF 5.0, however, provides its own scrollback mechanism as part of its virtual window model. I recommend upgrading to 5.0. Your terminal's scrollbar will not work, but PageUp/PageDown keys will work on most terminals, and other keys can be configured for terminals where they don't. In particular:
> Note for Mac OS X Terminal.app users: by default, Terminal.app traps PageUp and PageDown keys itself and does not send them to the application (tf). It does however send Shift-PageUp and Shift-PageDown to the application, so you can use these to scroll in tf running inside Terminal. You can also tell Terminal to send the unshifted keys to tf by redefining them in Terminal | Window Settings | Keyboard.
