Used to work.

It used to work. I have it on a new SE and now it shuts down after about 30 seconds if I look at an old message. Very frustrating. So if you can read fast its good.
And it hangs with an "ok" at the top of the screen which negates all time out security options (but I guess thats OK because it will likely crash before you actually can read anything).
