yeah. i've had it crash w/ plus shell before, and it takes a WHILE, even with
all 5 batteries out, before it actually resets (as opposed to 86 where one
battery for half a second takes care of it). anyway, my calc is still in
working order.
btw, i went to the self test screen cause i was messing around, and noticed
that after i exited, the bar at the bottom of the screen disappeared. is
there anyway to get it to reappear, w/o resetting memory?
