SO I first noticed this when typing a lab report and every time I pressed shift the computer played a beeping tone. then when I was playing overlord 2 and I pressed shift to target something and my magic was cast. A few days ago I spilled soda on my keyboard and then an hour later spilled water all over my keyboard, which may very well be the cause. I cannot type capitalize any letter that has an alt command associated it. Does anyone know how to fix a problem where your shift key acts as both your shift key and alt key?
