suddenly and inexplicably fucked

[the...@gmail.com]

My arduinoboy worked perfeclty. Until today. Now, when i power it on
(via USB), it goes through the normal test light sequence, but then
the MODE 3 light goes on. And stays on. Button presses have no
effect. If i reboot the device, with the reboot button, (that button
works), sometimes it will work. i can go through the modes, but once
i cycle through the modes, back to mode 3, the red light comes on, and
the mode 1 light comes on. And tey stay on. They won't shut off, and
nothing else happens or works.

i keep checking the circuit to make sure nothign has changed. no
shorts, etc... but everything seems fine. I use the diode meter on my
multimeter to make sure everything is getting through where it should
be getting through.. it seems all okay. I can't imagine what would
cause this behaviour, any ideas?

why is MODE 3 now always the default, and why would it stick on mode
3?

i tested the botton, it works.

It succesfully uploaded the latest arduinoboy software...
