1) This is not "game business" so the thread should be moved to "starting with gamestudio".

WINSTART
With the Pro Edition you can change the engine's behavior before start and after finishing the application. By default, on startup a small window will be displayed, which displays engine system messages and then waits two seconds before starting the application. However, with a WINDOW definition you in the .wdl file can omit that window, or create your own window with buttons, pictures, greeting messages, your company's logo, or a progress bar.
