We had the same problem. A very simple way to fix this is to change the values the camera goes to for pan and tilt when it begins a new search. Where the code is for the new search check, we changed our code to this...

if(new_search == 1)
{
	new_search = 0;
	//temp_pan_servo = 0;
	temp_pan_servo = (int)PAN_SERVO;
	//temp_tilt_servo = TILT_CENTER_PWM_DEFAULT;
	temp_tilt_servo = (int)TILT_SERVO;									
}

We commented out the old values and just changed the search to continue from the current servo positions (you will notice a temporary "freeze" of your camera when it outputs the same values for a second time after it finds and loses the target in the sweep).
