    I've the same problem that this post (
     When I have more than 8 items, Drag&drop crashes on the "CumulativeValue" method in IndexTree class.

    I think that this problem due to the constructor of IndexTree class : 

    internal IndexTree(int capacity, double defaultValue)
              this.count = capacity;
              this.size = 8;
              while (this.size < capacity)
                  this.size = this.size << 1;
              this.tree = new double[this.size << 1];
              this.itemDefaultValue = defaultValue;

    When you drag an element, i think this element is temporary duplicated. So "size" property is smallest
    is there a trick to solve this problem  ?

    Thanks to your help.
