I think maybe there are some old habits here that were learned on old BB devices that aren't necessary with QNX.
As an experiment...DO NOT PULL YOUR BATTERY when you are tempted to do it and instead try in this order to resolve and only move to the next item if the previous didn't work...
1) Wait a minute for it resolve itself
2) Swipe and Close the offending app
3) Power off and restart.
There is also the 5x swipe move to reset the hub if that is ever necessary.
