screen and curses(?) output

[paul beard]

I have discovered the joys of screen to manage processes between/across
logins, but I have one small problem. If I run portupgrade and a dialog is
displayed, I can't choose any of the displayed options. A tab will move
through them but a space bar or arrow key is the same as hitting OK with no
changes. is there some setting or different termcap I should use?

this is what stty -e displays:
