well, having prob with my laptop keyboard and i think i need a second opinion on my theory a "line" in my laptop keyboard doesn't immediately work, the " 2 w s x " line (look at your keyboard) and what i mean is this: i live in a cold place, and i don't place my laptop in its bag, so naturally the laptop gets cold now, when i open it while its cold..... that "line" doesn't work but after playing an hour or so and the laptop warms up, it works again.... now... it could be that BUT heres the thing... most of the time...it doesnt work when i play other games.... but when i play warcraft, after exiting it, the keys work again..... arrrghgghgh!!!!! its getting annoying, so i think i have to troubleshoot some more but i need your opinions....
Hmm. Strange problem. Not really a solution yet, but try using an external keyboard first. Just connect one -usb or otherwise- and see what happens. Just to be sure your keyboard is to blame. It might just be a weird virus messing with your system.
