ok, now read about this other bug I found (excerpt from an e-mail):
Some times when the ClassPad enters power save mode the buttons on the classpad will cease working, the stylus still functions, but none of the keys will respond (ON/OFF, Keyboard, EXE, etc...) thus making it imposible to do much more than navigate the menus. from what I can tell the only way to fix the problem is to hit the "P" button on the back of the ClassPad.
what I need help with is finding out if anyone else has encountered this problem, and if so what were you doing when you noticed. the people at casio havent been able to reproduce it themselves but if someone else has had it happen it could save them some time (and money) trying to figgure out if its just my calc, and then we might be able to help them in other ways if its not just mine.
I cant test this bug very easly myself because you must wait at least a day for the classpad to go into powersave, but if we all try things will go much quicker.
anyway, if this has happend to you or if you intend to try to test it, report back here.
