lost side, rear, down views; airplane parts blocking views

Suddenly now when I am in 2D cockpit view, eliminate panel completely (using 'w' key), then try to look right, left, straight down to ground, or behind aircraft, the airplane parts blocking those views remain. I have been downloading/adding planes recently, so I don't know if that messed something up (this problem is happening on standard aircraft that come with FSX), or if I just pushed a wrong button or something - ? I appreciate any help anyone can give me! Thanks!
