I haven't used android since first getting the box.
If I remember rightly it was a bit of a faff pressing the right button in the boot menu to switch OS's but either the android side or the E2 side gave you the option to reboot to the other OS.
I don't finish work until 11pm but might get chance to try it in the morning
I'm sorry, I've never used Stalker and I don't have anything to test it with at the minute.
