Hello,

I am not sure why you were not getting this exception with the previous build however this is thrown when your program accesses a GUI element from a thread other than the main thread. You may use the Invoke or BeginInvoke method of the control to execute the call.

If the issue persists then please attach a sample application (as it seems to me that you are using LocateDataSource event). If possible, please attach sample data as well so that we can check this further at our end.
