Balazar window will not close if pressing X button in top of windows

Binary package hint: balazar

1) lsb_release -rd
Description: Ubuntu maverick (development branch)
Release: 10.10

2) apt-cache policy balazar

3) What I expected to happen is that when I open Balazar, then immediately click the X button at the top left of the screen, the window closes.

4) What happens instead is that the windows does not close.
