I cannot configure Nanny :( I cannot change nothing - I tried to set computer usage hours and other restrictions but cannot mark hours graphically as expected.

I use Ubuntu 12.04 LTS 64-bit with all updates to current date (10th February 2013).

Steps to reproduce:
1. sudo add-apt-repository ppa:boamaod/nanny-test
2. sudo apt-get install nanny
3. sudo nanny-admin-console
......
Reconnecting to new nanny server instance
