Xenio: your info suggested to me that the problem is not the DPI but the aspect ratio that is the problem. I have a 16:9 monitor and your resolution as listed is higher than a regular 4:3 ratio. You may be able to try a work-around that I am able to use: After clicking the Summary button, press the right arrow key several times until the edge of the border of the key to the right appears. You can then access the Firewall settings by pressing Enter, or you can press the right arrow key again and then press Enter to access the Defense+ settings. It is a clumsy way of doing things, but it works for me. The next version will iron that wrinkle out, I expect.
