If the Keyboard isnt working for you it's because you installed the .cab to your storage card. There are scancode files in it that MUST go in the \windows folder, but installing it to a storage card puts them in \Storage Card\Windows.

Uninstall and then reinstall to main storage and the keyboard (soft and hard) will work just fine.

Thanks so much for this, Finster. This beats every other WM RDP client, hands down.
