We've had to turn off the camera, re-start the gui app then turn camera back on. It works again for awhile, then hangs up again.

Also, the first set of calibration instructions are confusing. It seems like we load the 2006 target.cfg file twice, and never save the parameters from the new illuminated target. I'm still scratching my head on this one.
Let's see... another hint that your hardware is giving you is the camera actually stops tracking ("Servos go left and down"). Once the application requests the camera to start tracking, it doesn't send anything to the camera until you click quit. It just listens for the tracking frames to stream in. If the camera stops tracking, that indicates a problem unrelated to LabVIEW. Chances are you'd experience something similar if using Kevin's RC code.

Definitely check the power.
