spot plane view display problems

For the last few months, I've been having problems with the spot plane view in FS9. The view looks like you're looking through a fish-eye lens. I have been unable to find a solution in the view settings. This only happens in spot plane view when I'm using a large(er) airliner - never with a Cessna. I have included a picture, taken from just off the left rear of a Northwest A319-114 at KMSP. The view has been zoomed out as far as possible in Flight Simulator. If there are any further questions, please ask. I'd really like a solution to this issue. Thanks!Mark
