Hi Patrick,
Could you please try disposing the dockingmanager in the form closing event handler
Private Sub Form2_Closing(ByVal sender As Object, ByVal e As System.ComponentModel.CancelEventArgs) Handles MyBase.Closing
Me.DockingManager1.Dispose()
End Sub
Thanks,
Stephen.
>I have attached a small example that demonstrates the problem. I have a dialog that has a docking manager and group bar on it with the group bar set to docking true. If I open the dialog from the parent and then close it. Then exit the app, I get the Windows applicaiton exception dialog popping up. If the group bar docking is set to false the problem does not occur.
