Hello Stefan,
Welcome to forums and thank you for your feedback.
NET2.0 doesn`t support transparency for overlapping controls and this`s your case when your control is overlapping the treeview. We can`t do anything here.
But treeview shouldn`t raise any exception in this case. Please tell us more or provide the sample code that generates an exception.
