For years, I've had this Logitech Quickcam Orbit. I love the camera. I decided to use it on my MacPro. Using it with FaceTime, I have found that it has an excellent picture. However, one negative. I'm unable to move the camera without just reaching out and moving it. I have searched and I have found a Logitech program for the Mac that will let me control it but only on a PowerPC Mac. What I'm wanting is to be able to use the pan, tilt and zoom on this camera. The face tracking, I'm not worried about. If anyone can help with a suggestion please let me know.
