You might want to see if someone has a Xoom device, since not many people have one it's not going to be easy.
See if you can let someone (like Paul) who is in the UK use your Xoom device and see what happens.
They need your device to fix the issue (since Android runs on just about anything including a Commodore 64, sorry can you tell I don't like Android). I just don't like the non existing standards, it's a nightmare to try to program on. Monkey another dev tool had many issues with android because of lack of standards and lazy platform planning.
Anyway, my advice is to contact Paul and see if he can get your device to fix the issues. It's obvious your device has some issues with AppGameKit and the only real way to fix it is for them to have that device so they can see what the issues are and since not many people have the device it will be hard to debug.
This would have been avoided if there was proper platform planning, I doubt ios or Windows Phone 7 would have these same issues.
App Game Kit (A.G.K.) - Want to be creative on many platforms at once? This is the tool you need.
