Hi, I have a problem with scrollbar on UltraTree control (also under 9.1v of Infragistics)

When I open a dialog form with tree to show available nodes i want to show currently select node in my application.

To achieve selection i use this piece of code

m_objTree.SelectedNodes.Clear();

node.BringIntoView();

node.Selected = true;

m_objTree.ActiveNode = node;

Opening this modal form causing strange tree look ( look at Attachment 1), the scrollbar does not work at the beggining... I cannot see the top of the tree/root. The scrollbar seems to come into effect when I move it. (Attachment 2)

Any ideas?

Thanks in advance.

Regards.
