lightening lines on screen

[jacko70]

I have just purchased the Mini ST15i and each time my finger contacts the screen a fine blue lightening like line follows where my finger has touched. The line is present on all screens I select. Not sure if this is a phone fault or something I have accidentally set up while experimenting with the phone. It was not present when I first got the phone which makes me think it is the latter. Anyone any ideas on how to rid me of these annoying  lines ?
