Sensor gets confused

[durf]

I have 4 sensors that I use currently for my program. Sometimes I switch the program only to track three, but the problem is the computer that tracks the sensors seems to switch sensors once in awhile. Is there a way to track 4 sensors, use 3 of them(for example, could be only 2 as well) in the program and keep the sensors inline(meaning not switching)?

I can explain more if this is not clear. Its kind of hard to explain whats happening. FYI, these sensors are single lights.

IE. My sensors are linked to a 'white_ball.wrl' (node). I labed the sensors accoreding to the label of the balls 1,2,3,4. I switch my program to disable ball 4. The problem, sensor 2 switches with sensor 4. so now sensor 4 is ball 2.

Is there a way to solve this?

If the markers get occluded then the ID's can switch.

The solution to this is a new product we have called Marker ID, which are markers with programmed ID's, and by blinking certain patterns, PPT will not get confused
