  In the below 1 form app GetNodeAtPoint doesn’t adjust for vertical scrolling and returns the wrong node. Otherwise the speed of scrolling is much improved. Please fix this quickly.

  Public Class Form1
  
  Private WithEvents tv As C1TreeView
  
  Private hoverNode As C1TreeNode
  
  Private Sub Form1_Load(sender As Object, e As EventArgs) Handles Me.Load
  
  tv = New C1TreeView
  
  For i = 0 To 999
  
  Dim n = New C1TreeNode
  
  n.SetValue(i.ToString)
  
  tv.Nodes.Add(n)
  
  Next
  
  Controls.Add(tv)
  
  tv.Dock = DockStyle.Fill
  
  End Sub
  
  Private Sub tv_MouseMove(sender As Object, e As MouseEventArgs) Handles tv.MouseMove
  
  hovernode = tv.GetNodeAtPoint(e.Location)
  
  If hovernode IsNot Nothing Then
  
  Debug.Print(hovernode.GetValue.ToString)
  
  End If
  
  End Sub
  
  End Class

  Hello Kingman,

  The build including fix to your issue would be released by mid-march.
  
  Also, since the release date is very close, it would not be feasible for us to share a pre-release version.
  
  Thank you for co-operation.

  Regards,
  
  Ruchir Agarwal
