What an idiot I am. The problem was that my desktop display settings were set for 1680 x 1050. My in-game setting was set at 1366 x 768. Once I figured out what the problem was, I made the corrections in-game and now everything is the way it's supposed to be, when upgraded to v5.04.. You CAN teach an old dog new tricks. Or, in this case, an old dog can learn new tricks.
Thanks for all your help, Polovski. Much appreciated.
