The problem is that the library does not support
clusters having mulitple unnamed elements. For example,
it stores data according to the following convention
Write Key (Variant)
[Sectionname]
Clustername.Elementname = Value
Write Section Cluster
[Clustername]
Elementname = Value
It is easy to see how a cluster with multiple unnamed
elements can cause old data to be overwritten, or cause
an error, in the canse of Write Section Cluster.
I think that the solution is to do something similar to
what NI does. If a cluster element does not have a
name, then call it "Element 1", "Element 2", and so on.
