I am running viewer from home: Windows 7 Home Premium SP1
I am viewing a remote computer at work: Windows 7 Enterprise SP1
I open Notepad for testing. I opened notepad and all of the alpha keys and the numbers across the top of them work. My number pad keys (right side of keyboard) also work until I turn off numlock to try any of their non-numeric function (up, down, home, end, arrows). After I turn numlock back on, those keys no longer work at all. Also, my arrow keys at bottom of keyboard do not work at all.
I just updated viewer and host, so both are at 18.104.22.168.
