Start the thread before calling ShowModal(), or have the form's OnShow event start the thread. Use the thread's OnTerminate event (which runs in the main thread) to Close() the form, which will cause ShowModal() to exit. While the thread is running, it can use TThread.Synchronize(), or custom window messages, to update the form as needed.
