TreeView crashes with more than 8 items?

[FENWICK]

Hi,

I've the same problem that this post (http://www.telerik.com/community/forums/silverlight/treelist/treelistview-crashes-with-more-than-8-items.aspx).
 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;
          this.Initialize(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.
