I can reproduce the bug 99% of the time now. Run program with sound, turn off, turn on, tap start button, tap application...

And it's hung - needs rebooting. Windows just seems to make the process hang.
Here's the messages it sends when it hangs

(Wave) Power Off/On, Start Menu
15:24:08 - 000f,3f3838 it's fine here
15:24:08 - 000f,3f3568 it's fine here
15:24:08 - 000f,3d0918 it's fine here
15:24:08 - FP 000f,3d0918 it's fine here
15:24:08 - FP 0014,3d0918 it's fine here
15:24:08 - 03fc,0 it's fine here
15:24:40 - 001f,3d0918 after turning back on
15:24:40 - FP 001f,3d0918
15:24:40 - 03fc,0
15:24:42 - 001f,3d0918
15:24:42 - FP 001f,3d0918
15:24:42 - 03fc,0
and the app is dead - no matter how much you click the screen, no other messages get sent.

What's going on, I'm mucho confused??
