just a idea but try cleaning your keyboard with wipes as maybe dirt/grease on the keys could be causing this, also i have just discovered an amazing product from the chemist a couple of months ago called BIO OIL it's amazing but quite expensive (�8.00 for 60ml), when i brought the first one i wasn't convinced it was doing anything, but by the time i started the 2nd one i knew it was, it's soooo good! I put it on my arms/legs/chest/feet and stomache every night and my skin felt noticebly smoother but i also put it on my hands as i have always felt my hands looked old as they were so dry and i have tried allsorts of handcreams but my hands now look wonderful and smooth and my nails and cuticles are really healthy just try it, sure it will help and its all natural too!
