I have a WPF app where a UserControl is created at startup. The control contains two SciChartSurface objects, both initially invisible. About every 10th time I start the application it hangs on the thread with this call stack:

mscorlib.dll!System.Collections.Generic.ObjectEqualityComparer<System.__Canon>.Equals(System.__Canon x, System.__Canon y)    
mscorlib.dll!System.Collections.Generic.List<System.IComparable>.Contains(System.IComparable item)

PresentationCore.dll!System.Windows.EventRoute.InvokeHandlersImpl(object source, System.Windows.RoutedEventArgs args, bool reRaised)

The CPU spikes and the app never responds. Any thoughts as to why this might happen?
