I had hell of a time fuckin with this key at times, driving me bezerk at times not wanting to work all types of shit but only spuraticly. Sometimes for a while. I had started using my phones stylus for the stylus phone and it would work if we did little circles sometimes and all this stuff. B buttons didnt work.
How many of you that have these problems have your laptop plugged in?
Unplug it and try again. This motherfucker has worked 100% of the time with the b slots too when its unplugged.
