Hi everyone i recently purchased a 2010 MBP 13" 2.4 320m. I notice when i scroll using the multitouch through pages i experience a choppyness in the scrolling. Almost as if there were a invisible horizontal line distorting portions of the text. It is very subtle but is definitely there. Has anyone had these issues? If so how did you remedy it, anybody have a "genius" diagnos the problem? Thanks in advance. P.S - I've owned the 2009 MBP 13" 9400m and never had this problem.
