iPhone sdk 3.2.3 upgrade Problem
<p>I just upgraded my Mac to Snow Leopard, and installed Xcode 3.2.3.</p>

<p>The app I am working on ran perfectly before the upgrade.</p>

<p>Now, the default image appears briefly, then the screen goes black except for the status bar. Same behavior on my iPhone 4 and in the simulator, whether I target iOS 3.2 or 4.</p>

<p>The app is still running and I an see from traces and in the debugger that the app is running normally, and my root view controller has been loaded, but nothing but blackness on screen</p>

<p>Anyone seen this before?</p>

<p>Thanks</p>

<p>JK</p>
