+I found the roots of the problem. Problem occurs when TreeView.Sorted
+property is set to True. First node of the tree node which is in fact
+invisible has it's Text property set to 'ROOT NODE'.
+
+This 'invisible' root node is TreeNode type, so that is imposible to
+cast it into the MyTreeNode.

+Attached source file reproduces the problem.
