Insertion point problems

I don't think traversal is the problem here. When I tested, my button did not have traversalOn set to true (that was the first thing I checked.) The anomaly is that the selectedChunk works fine if the selection contains text, it only fails if the selection is a simple insertion point. 

Both instances should work identically.
