Hello.

We are currently using the Nevron UI libraries and employ the NTreeView in our code. Whenever the user is scrolling through the tree, and either holds the up/down arrows, or holds on the scroll bar, the user is presented with a dialog box for an unhandled exception. This dialog box gives the option of "Continue" or "Quit", and if the continue option is selected, the application continues with no apparent consequences.

The dialog box also provides the exception stack trace, shown as follows:

System.NotImplementedException: The method or operation is not implemented.
at Nevron.UI.NVisualElement.OnTimerTick(Object sender, EventArgs e)
at System.Windows.Forms.Timer.OnTick(EventArgs e)
at System.Windows.Forms.Timer.TimerNativeWindow.WndProc(Message& m)
at System.Windows.Forms.NativeWindow.Callback(IntPtr hWnd, Int32 msg, IntPtr wparam, IntPtr lparam)

Is there an updated set of libraries we can use to circumvent this problem?

Thank you.

For reference, the version of the dll's (as displayed in Visual Studio 2010) are:
Nevron.Diagram: 12.5.9.12
Nevron.Presentation: 12.5.9.12
Nevron.System: 12.5.9.12
