@TaoManJoe: Err, yeah, looks like you've set up some stuff without knowing, because it definitely *doesn't* build covers on its own by default. There's a "Reset to default behaviour" button in the KUAL menu bundled with the hack, see if it helps (after a restart, which was and is indeed a good idea
).
@GoSharks: Gah, I forgot to put the "don't boot with the device plugged in" thing in the FAQ, did I?
EDIT: Yup... Amended the FAQ, thanks
