    copied!<p>I've created an RCP application with an interactive splash for logging onto my system. I built it on a Mac, and the application works perfectly, but when I created a new product configuration for Windows and run the application, it launches without the splash and there are no errors appearing in the console.</p> <p>The splash handler code is as follows</p> <pre><code>/** * The splash screen controller for the RCP application.
