title: wx SplashScreen doesn't work
body: <p>I've used the sample code from the wiki but it just doesn't work for me, I see nothing. What am I doing wrong?</p>
  
  <pre><code>import wx
  
  app = wx.App()
  
  aBitmap = wx.Image(name = "wxPyWiki.jpg").ConvertToBitmap()
  splashStyle = wx.SPLASH_CENTRE_ON_SCREEN | wx.SPLASH_TIMEOUT
  splashDuration = 1000
  
  splash = wx.adv.SplashScreen(aBitmap, splashStyle,
                                   splashDuration, None)
  splash.Show()
  wx.Yield()
  </code></pre>
