I just had a heck of a time ungrappling from the payload. I'm on a Mac without a numeric keyboard (but with a joystick) and it wouldn't acknowledge the num5 key that's mapped to the joystick. I had to get the WinXP on-screen keyboard up, and turn the numlock on for it to recognize the mapped command!
The wonders of a laptop... (and Apple).
This qualifies as a great hack in space, my friend! Mission must be accomplished even if hardware fails. That's a true explorer's spirit. You're on your way to becoming a seasoned virtual Astronaut!
