OK, I went on with the recon mission and when I got into the harbor and relatively close to the target, the camera became active. This worked both with and without the "camera mod." It appears that the use of the periscope camera is mission dependent and not a fulltime option. Thanks for the inputs and discussion. This forum is great, since a newbe like me can ask questions without being chastised for ignorance. The game is great! By the way, I am using an ASUS motherboard with dual-core AMDs and Nvidia 7000 series video. It works great. Thanks Old_tex
