It could be a transient issue, since I do believe that Ben and I are both
using 0.2.1+ versions. I'm really hoping that it's not your kernel patches
:). Did you try the unmount/unload all usb drivers + njbfs / reload thing?

I'm not sure if an update is wise... perhaps creating a new project within
the repository would be a better idea?

Speaking of time, I should apologize for not spending enough on the
project. I just have to get these two weeks of exams, and I should be
good. If I had better time management skills of course, that would help.
Or perhaps waking up earlier :)

Those could be us artificially inflating the count :). Actually, I've seen
a lot of different users (I think).

I'm going to try to duplicate it with my setup. My thinking is that if I
remove the batteries, leave it on AC power and then yank the code I should
be able to replicate what happens on a power down. Although I think the
NJB sends a few signals up the pipe right before it powers down? This is
going to be hard to trace though.
