My keyboard has been going haywire the last few days. Keys are misfiring and it is impossible to type. for example: weitrIO ]'totpesometirealluy basic keys misfire and the space bar does all sorts of wierd stuff.TadfgEQW**æ and te y makeallsort.. and then it will be fine for a little while and then all of the sudden it will go nuts again. Its a unibody mid 09 model so its out of warranty. Seems like maybe its a software thing because all the keys do in fact work, just not always how i want them too.
