I created an Xcode project to illustrate the problem I'm having with UIAlertView. You can see the result here:
Here is the Xcode project to recreate this problem on your machine. It's pretty simple - but if someone sees that I've done something stupid, please feel free to call me out on it. In fact, I want to encourage it, so the first person who can show me something I've done wrong in this project that is causing this problem with UIAlertView is welcome to a free copy of Beginning iPhone Development, if they want it.
