I am working with a Panasonic Model P50, serial number TD 8245948 Apirl 1998. Somehow the on screen menu setting must have been changed because when a page is displayed the screen has a stretched look to it and some of the buttons or scroll bars on the right or left cannot be seen or used. This is a problem I need to resolve as quickly as possible since this is the main business computer. I appreciate any help or suggestions you may have to have.
