view change ctd

Hi,Im having problems with fsx crashing when cycling through views. I remember having this same problem before and it seemed to be when pressing s and going past the nearest tower view option this was when it would crash. Now im sure there is a way to take out the nearest tower view when pressing s so that it doesn't display, but for the life of me i cant remember how to do it. Ive searched high and low on here but cant find anything. Maybe someone can remember and remind me. I think i have to change something in the cfg file but not to sure what. Many thanks for any help.
