g.help

I have what must be a simple case of brain fade on my part but never the
less...
on a SUN IPC under OpenWindows 2.0, the g.help command brings up the dialog
for selecting a topic, but the commands for moving the asterisk to the topic
of interest do not seem to work properly. the down and up keys move the text
but the asterisk (and the topic selected) seems to stay at the top of the window
as the text scrolls by. Naturally, this makes some of the items in the list
inaccessible. Can anyone suggest what the problem might be?

Thanks,

John
