Hmm formatting went a bit astray

I get the following exception when drawing a chart. The exception is intermittent and I can't tie down what cause it.I've just installed the 6.2.3188.26800 SP but it makes no difference. The OS is Vista SP1. ************** Exception Text ************** System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation. --->

I can add annotations to a scatter chart. I then want to reuse the chart and so do: this.chart1.ClearData(SoftwareFX.ChartFX.ClearDataFlag.AllData); this.chart1.Extensions.Clear(); but when I add another annotation I get the following exception:(Running on Vista and .Net 1.1) System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation. ---> System.NullReferenceException: Object reference not set to an instance of an object. at SoftwareFX.ChartFX.Annotation.AnnotationList.0O(IGraphicsEx AQ, Rectangle AR, Boolean AS, Boolean AT, Int32 AU, Int32 AV) at SoftwareFX.ChartFX.Annotation.AnnotationX.24(IGraphicsEx F3, Rectangle F4, Boolean F5, Int32 F6, Int32 F7) --- End of inner exception stack trace --- at System.RuntimeMethodHandle._InvokeMethodFast(Object target, Object[] arguments, SignatureStruct& sig, MethodAttributes methodAttributes, RuntimeTypeHandle typeOwner) at System.RuntimeMethodHandle.InvokeMethodFast(Object target, Object[] arguments, Signature sig, MethodAttributes methodAttributes, RuntimeTypeHandle typeOwner) at System.Reflection.RuntimeMethodInfo.Invoke(Object obj, BindingFlags invokeAttr, Binder binder, Object[] parameters, CultureInfo culture, Boolean skipVisibilityChecks) at System.Reflection.RuntimeMethodInfo.Invoke(Object obj, BindingFlags invokeAttr, Binder binder, Object[] parameters, CultureInfo culture) at SoftwareFX.ChartFX.ExtensionManager.MH(19 2BV, Enum 2BW, Object[] 2BX) at SoftwareFX.ChartFX.ChartCore.EO(1R 1SM, Boolean 1SN, Boolean 1SO) at SoftwareFX.ChartFX.ChartCore.EN(1R 1SJ, Rectangle& 1SK, Int32& 1SL) at SoftwareFX.ChartFX.ChartCore.EM(PaintBar 1SG, IGraphicsEx 1SH, Rectangle& 1SI) at SoftwareFX.ChartFX.0X.OnPaint(PaintEventArgs e) at System.Windows.Forms.Control.PaintWithErrorHandling(PaintEventArgs e, Int16 layer, Boolean disposeEventArgs) at System.Windows.Forms.Control.WmPaint(Message& m) at System.Windows.Forms.Control.WndProc(Message& m) at System.Windows.Forms.Control.ControlNativeWindow.OnMessage(Message& m) at System.Windows.Forms.Control.ControlNativeWindow.WndProc(Message& m) at System.Windows.Forms.NativeWindow.Callback(IntPtr hWnd, Int32 msg, IntPtr wparam, IntPtr lparam)
