Screen Orientation in Ice Cream Sandwich?

Hello,

First time posting here.  I've got an app that I run in just landscape mode.  I force landscape mode by doing the following in the app.xml file:

     <initialWindow>
         <autoOrients>false</autoOrients>
        <fullScreen>false</fullScreen>
        <visible>true</visible>
        <aspectRatio>landscape</aspectRatio>
        <softKeyboardBehavior>none</softKeyboardBehavior>
    </initialWindow>

This has been working perfectly.  However, I recently got a Galaxy Nexus (with ICS) and when I run the app on there, if I lock the screen with the app open, when I unlock it, the screen is in portrait and I cannot change it back to landscape without restarting the app.  I tried doing stage.SetOrientation when the screen is activated again to see if that would be a fix, but this causes the phone to completely freeze when I attempt to unlock it.  The app works as expected on other phones, so I'm guessing this is an ICS issue.  Anybody know a workaround?

I appreciate any help. I've spent quite a few hours and time searching for an answer to this, but haven't had any luck.  Thanks!
