Bug#454585: Whishlist: Update-manager grabs the focus when pre-configuring the packages.

[Avery Fay]

Well, I don't know who's fault it is, update-manager or 
dpkg-reconfigure, but programs that don't have focus really shouldn't 
grab focus from other programs. I just hit this bug myself because I was 
  in a terminal at the time and hit enter. I have no idea what question 
I answered and what the default I selected was. I actually consider this 
a pretty significant usability bug.
