Stuck when launching MetroWindow in a Separate Thread

Describe the bug

This is the code with problem. SplashThread = new Thread(new ParameterizedThreadStart((state) => { var wnd = new MetroWindow(); wnd.Show(); Dispatcher.Run(); })); SplashThread.SetApartmentState(ApartmentState.STA); SplashThread.IsBackground = true; SplashThread.Start();

Steps to reproduce

Expected behavior

Show a window before main window shown.

Actual behavior

Program stuck in line wnd.Show().if I modify the code like this, use Window instead of MetroWindow.

SplashThread = new Thread(new ParameterizedThreadStart((state) => { var wnd = new Window(); wnd.Show(); Dispatcher.Run(); }));

The window show normally. Is there anything I do wrong?

Windows build number: Win10 1909 [Version 10.0.18363.836]

Exactly. Fixed that already. We just have to release a new version of ControlzEx. I also made the PInvoke-Wrappers we have there appear in the StackTrace again.

I will close this here for now, the final fix will be available with the next release of ControlzEx.
