[jitsi-dev] Splash screen isn't shown when Jitsi starts (after install)

During development, I can force the splash screen to be shown if I put the
following in build.xml :

<property name="jvmarg.splash"
                  value="-splash:resources/install/resources/splash.gif" />

However, if I build an installer for Windows, run it, and then try to run
jitsi via the installed jitsi.exe file, the splash screen is not shown.

Is there any solution / workaround to this, or any file that needs to be
changed so that the installed exe will show the splash screen?
