Errativ View Change

I really like the B58 in all respects.. until its time to land. When approaching airports (in particular) FSX jumps to the next "View" as if I had hit the Cycle View (S key)) however, my "S" key is disabled to accomadate EZDoc. It is really annoying especially on short final. In fact, its maddening. . Is ther possibly a setting that may be causing such errativ behavior?
