Following 1-4 is the procedure for reproducing problem.
  1. launch sample app
  2. play something movie
  3. minimize the app to task bar
  4. relaunch the app via tile button
  5. (sometimes) the app freezes
This problem occured in both javascript and xaml versions.

Especially javascript version is often occured this problem.

Are there any idea to avoid this problem ? or Is this an inevitable phenomenon ?
