Thats funny..i get the same thing with some other apps..
I click the icon.. the Default image zooms in, and BANG! quits out and back to the main menu...
that Pokerist.com game does it on my iPad iOS 3.2 as well as a few other apps.
no amount of deleting and reinstalling helps..
Best thing may be to email the developers and tell them what device you are on and what version of iOS you have installed.
