Thanks for the quick reply. There are no explicit threads in the application. I should have included that the app was written as a form app but we recently modified it to not display the form removing the Application.Run call in the DPR and executing a method instead:
Application.CreateForm(TForm1, Form1); Form1.RunApplication; //Application.Run; The Form1.RunApplication method was factored from the Form1.FormShow method (without the UI specific code). Thinking about it, this is likely the cause. What does Application.Run do, specifically cleaning up, that could be missing? (Maybe this is a question for another forum).
