2008Q2 throws an exception if you add the same TreeNode twice to a Nodes
collection, while 2008Q1 allowed (or silently ignored) this.
Actually found a coding error in my test app, where the same child node
was added multiple times. The exception message could be friendlier ....

Hi Erwin,
Thank you for writing.
There was a undocumented behavior of the Add method that allowed the method to be called with a node that is already in the collection. In the Q2 2008 version that behavior was fixed and it is expected to get an exception if you are trying to add/insert a node that is already in the collection. The Move method should be used if you want to move a node to another position in the same collection.
However, I admit that the exception message was indeed unclear and we have changed it.
Best wishes,
