The Program Control Window is the one where you can review and alter the firewall rules for particular executables.
In the prior NIS 2011 version (and in NIS 2009 and 2010), you could maximize this window to the size of the desktop by double clicking on the title bar. This functionality has been lost.
Although not a major problem, the ability to only use a fraction of the total desktop display is an unnecessary inconvenience.
Thank you.
