The test freezes when trying to perform multiple actions in parallel. Here's a sample code: Parallel.Invoke ( () => {Actions.SetText(Pages.ClientLogIn.GeneralBoxContentUcClientRegistrationScetbLastNameTbSanitizedText, "test");}, () => {Actions.SetText(Pages.ClientLogIn.GeneralBoxContentUcClientRegistrationScetbFirstNameTbSanitizedText, "test");} ); If we comment the first action, the second will run just fine. To reproduce: Sample project is attached to the internal description.
