aptitude freezes after install

[microwaverich <richgrif@one.net>]

I upgraded from Etch to Lenny yesterday.  Now aptitude isn't behaving 
properly.


When I enter a single command at the command line, like:

aptitude install xawtv

it works fine.

If I just enter 'aptitude' to start the full-screen (ncurses?) version, 
when it completes an install it stops responding to the keyboard.  I can 
abort using CTRL-C, but nothing else seems to work.

Advice?
