I too am having the same problem, I am using v4.1.0.62 and anytime I cause the node to collapse programmtically it crashes with the same error as above. Both .Expanded =
False and .CollapseAll cause the same error.

I was able to overcome this issue by calling TreeView.Focus before calling TreeView.CollapseAll
