CameraRoll.browseForImage() does nothing

I'm developing on an iPad Mini with iOS 8.1.3 and using Adobe AIR 17.0.0.144. When I call browseForImage() the screen seems to flicker (only the first time I call it) but do anything. Touching anywhere on the screen will trigger a CANCEL event from the CameraRoll as if it were open but hidden. Is anyone else seeing this? I hope this can be fixed soon.

Thanks,

Shane
