DC3 panel problem

Hello,For the past several months, I've flown my DC-3 with no problems. Then, last week, I booted up and found the following:1) From the Pilot's Seat, if I click on the "CP" icon, I'm switched to the Co-Pilot's Seat view. Perfect. No problem. But if I use the keyboard command (Shift+3) for the same purpose, I get the Co-Pilot's Seat overlaid, with the previous view remaining, so that I see two compasses, etc. 2) The hat switch, which in spot mode allows checking out the exterior of the aircraft, always worked in continuous mode -- that is, if you held it in a particular position, the motion would be continuous. Now it only moves in a tiny increment, and to go further you have to click that direction again.Any ideas what might be causing these changes? I don't see it as a hardware problem, but something in the software that I may have accidently set.Thanks for any feedback.Gary
