So my usb KB was looking pretty grungy so got the bright (or not so bright) idea of cleaning it with windex. I sprayed a little on a paper towel and tried to gently clean the grunge off the keys. It is now clean, but the "D" and "E" keys do not work. Its been three days also so I figure if some liquid did spill under the keys they would be dry by now. Is it ruined? BEtter yet, is this a good excuse to buy a new imac?
