In Flexible Program(with a P and *) you can select the shutter speed on the D90. The camera selects the proper
aperature for correct exposure. When you rotate the command dial and the aperature/shutter speed does not move it is because, while moving the command dial a correct exposure can't be obtained. Rotate the command dial a few times in the other direction and the shutter speed will change for the proper exposure. Now, if you keep going in that direction at some point a correct exposure can't be obtained and the shutter speed/aperature will not change. In summary the aperature/shutter speed will change only in the proper exposure limits. Hope this helps.
