Friends not integrated with global menu & sticking to left of the screen

After upgrading from 12.10 to 13.04, Friends app was installed, but when I run it, it opens in the left of the screen giving no hand to be re-positioned, minimized, or closed (unless I press CTRL+F4). See attached screenshot. Otherwise, it stick on the left of the screen, its GUI header and footer are unreachable.

Commands like: sudo dpkg --configure -a or sudo dpkg-reconfigure friends or even sudo apt-get install --reinstall friends
did not help.
