Updated from NIS 2012 to 2013 without incident and it seems to be work well. Found one problem. When opening NIS 2013 from the icon in the System Tray the initial window is in a simplified format with big buttons. Clicking on the Advanced button does bring me to the advanced view which was the default in NIS 2012. Then clicking on the pin will cause the Advanced view to be "pinned" but when I did that part of the animation of the large buttons moving off to the left keeps repeating and I could not un-pin the Advanced view to stop the repeating animation. Eventually after many repeated clicks I was finally able to un-pin it and the animation stopped but I could not close the window. Rebooting restored NIS to normal but I have not tried to pin the Advanced view (although I would prefer that view) for fear of the same thing happening. Definitely a bug in an otherwise problem free program.
