Looks like minimenu is showing in the background; assuming an unmodified minimenu usage, hitting Pandora shoudl kill the running pnd-app, and that in turn would cause minimenu to come back up; would be curious to know if the app is still running (did it fork off something?), but probably its just done some ofbset type magic to fiddle with screen layering, and perhaps that doesnt' get properly unset when the app exits.
I wonder if pnd_run.sh needs to forcibly reset the display to 'known state' on app exit?
