This is the face i showed when I noticed that,even when the pen was not touching the surface of my wacom,it was drawing a thin line whenever I moved it!!!!!

Yes,if I hold the pen about a centimeter above the surface of the tablet,the green light turns on,as if it was touching it and so it draws lines messing the whole piece!!!!!

Help!!!What can I do to solve it???I instaled new drivers and made a recovery system but the problem stills there!!
