Not sure if this was due to temperature, but the other day when I was playing WoW on my MBP, it suddenly went all weird. The resolution got bigger and the desktop screen was moving with my mouse, kept moving out of the screen whereby the dock disappears (it appears again when I move my mouse upwards). Had to reset it and everything was fine again. Should I be concerned? Anyone have any idea how this happen? Btw, when I play WoW my mbp temps on iStats runs at about 80 degrees constant (both cpu and gpu), is that normal?
