Have you tried force-quitting the app and restarting?
Double-tap your home button and locate the Messages window, then swipe up on it to make it fly off the screen. Hold down the Power/Sleep button and the Home button until you see the Apple logo, then let go. You won't lose any data doing this but it will be a restart procedure.
