[hypotyposis]

I'm having a different problem post-4.2.1 update: my inbox got "stuck" after I checked off two items; the first one went fine, the second one remains on the screen (checked off and struck-through), and although I can scroll up/down in my inbox, I can't open any action again. Just mailed the ninjas about this. (I'm assuming once I sync back to my Mac this should take care of it, but that could become a major problem if it turns out to be recurrent.)
