how get cluster element value change event

[jmerrill]

The event processing is the way to do it. Comparing huge clusters of controls is going to take a lot longer-and the memory manager has to make copies of all that data to compare it, and create a new same-sized cluster [struct array] of booleans.

I'm sure if I benchmarked these two methods it would not be close.

Make a Reference to a cluster element and register that Value Change event. It'll fire on all changes if in an array though.
