I don't have any of those platforms available to me, but I'm using the
same version of dialog on Debian Testing.

To test out my version of dialog, I ran the following command:

    for thing in `seq 1 100`; do
        echo $thing
        sleep 1
    done | dialog --programbox 10 20

...which, as you might imagine, prints one number per second,
live-updates the last 8 in a dialog-box, gives you an OK button when
done (no scrollback) and exits when you click it.

Interestingly, if I run the command:

    printf 'hello\nworld\n' | dialog --programbox 10 20

...then I get an empty window with an OK button (I suspect the divider
line and the button push the first two lines of output off the top of
the display).

I don't know what might be causing the behaviour you describe, but if
the examples I've pasted above work then I guess there's something wrong
with your invocation. If they also don't work on your systems... I guess
you'll need to keep digging.
