iOS Splash Screen masks display

[Graham Samuel]

I'm developing an iPad app which has an iOS splash screen (they all do), which AFAIK is there in order to show itself until the app is fully loaded. I am not sure how iOS knows that the load is complete, but anyway I seem to have a problem about this.

My app has two stacks: the first has a startup handler that sets things going but is not displayed, and then hands over to the other stack. When the splash screen goes away, I want to show a particular card (say Card1) in the second stack, wait a short time and then move to another card (Card2) to allow the user to start work. I found that if I put a script like this into the first card:

on openCard
  wait 4 seconds
  go to "Card2"
end openCard

then the splash screen stays around for an extra 4 seconds, and the first thing the user sees is Card 2 - Card 1 is never visible. 

What did I do wrong and how can I get the result I want?

TIA
