Hi there. I have a three month old 21" iMac. I have it plugged into an extension cord. I asked 3 apple people if this was OK to do, and everyone said no prob. My problem is when I run my hand along the metal parts of my screen, it is electric!! Like feels like its vibrating and buzzing..... today it actually shocked me and kind of hurt. I tried looking many places to see if this is normal, but it is not seemly so..... anyone know anything I don't??!
