macbook pro electric shocks

Have had my Macbook Pro for just over 12 months and since day 1 - if i use the 3 pin plug i get electric shocks from my Aluminium Unibody, its the same if i fit a European type plug but NOT if i use the long flex lead - i think this is because it has an earth...

So - why is my Mac giving me shocks, and does anyone else have the same issue?

I know its not just my Macbook Pro - i bought my daughter an iMac 21" last month and i was trying to plug a USB printer in to it in the dark and as the USB connector made contact with the aluminium body there were sparks...

anyone else find this?

MacBook Pro, Mac OS X (10.7.4)

Well, Pete, read these posts, and you will see it is a wider issue. I find it more than just annoying - occasionally it's strong enough to be a pinprick or feels like a splinter. Or, to mirror what others have said, it feels like a sharp edge or a burr on the metal of the case... I have a skin on my computer, so my arms/hands touch in just one small place (the bare edge of the case), which may mean a more concentrated current. I'd suggest testing a wider variety of devices, under various circumstances.

I have a 2009 17" max pro and 3 prong long charging lead (AU).i receive a tingling sesnsation every time I touch the Mac. If I make contact with someone while touching the case they receive a shock. This has been ongoing for a couple of years.

I'm using the earthed lead and it doesn't matter what surface I'm on, I still get shocked.
