  … trying to figure out the problem. Note: the application is multithreaded. Once in a while this exception happens:

  System.InvalidOperationException: Object is currently in use elsewhere.

  Trace:

  Can you help point us in the right direction for seeing how to fix this?

  Hi,

  It’s very difficult to find the cause of this from the exception alone. We can only infer that you are having issues in synchronizing access to a resource.

  If you can replicate this in a small sample and show us, we would be able to help you more appropriately.

  A more general suggestion would be to make use of BeginInvoke (https://docs.microsoft.com/en-us/dotnet/api/system.windows.forms.control.begininvoke?view=netframework-4.8). However, this would depend on where and when you’re getting this exception.

  Regards,
