No, on OSX the dock icon sits and bounces until the application polls the carbon event loop the 
first time. The application.processmessages that is required to get the splash screen to draw 
properly does this and therefore stops the dock icon bouncing a lot earlier than if it waited for 
the main form to finish loading.

The load time from click to usable is identical in each case. One shows a splash screen and the 
other just sits there with a bouncing dock icon until the main form comes up. I know which one I prefer.

I'm not really familiar with OSX development, so it was just a nice bonus for me :)
