Thanks. I did try that with the same result. If I set up a particular view and the enter for example ctrl-numpad 6 the view just shifts slightly to the right. Or ctrl-numpad 2 the view just shifts slightly down. Whether or not the numlock ket is set or not same result. I wonder if somewhere as I way playing around with the new program I entered something that just messed up a config file somewhere. In any event I deleted the X-Plane 10 folder and have re-downloaded and installed the program. I'll see if the same error occurs. Thanks very much for your suggestion.
