Sometimes unable to stop recording data.

[thetorpedodog]

Sometimes, when you start recording data and later return to the app to stop recording, you cannot press the “stop” button to any effect.

Steps to reproduce (flaky):

1. Start recording any experiment. (Light sensor works well because it’s cheap.)
2. ??? (For me, this usually involves letting the device sit for a while, it going to sleep, and waking it back up after several minutes.)
3. Reopen Science Journal and switch back to the observation tab.
4. Tap the stop button.

Expected result: Tapping the stop button stops recording and saves your data.

Actual result: When you tap the stop button, nothing happens—data recording continues and cannot be stopped except by force-stopping the application.

I’ve had this happen multiple times (including just earlier today) but haven’t been able to work out a consistent way to repro it.
