Bought a new 15" MacbookPro Aug 2013. From start, probs with cursor moving & adding,e.g. end of word somewhere else in text. Last time Apple replaced top case. Sympton: "trackpad cursor not tracking properly" I still have same problem with trackpad cursor frequently but unpredictably moving taking the remainder of the word,paragraph with it. It does this in every program, mail, safari, notes, pages. it also does this when I'm dictating but you can only see this on the computer screen as on the iphone you can't monitor how the speech recognition process proceeds as it tries to figure out what was just said. (I just corrected one of these errors which just occurred.)
I've been in at least 4 times since august 2013. They just replaced the topcase which I thought would fix the problem since that means the cursor was replaced as well according to the people at the store I talked to.
HELP!
MacBook Pro (Retina, 15-inch, Early 2013), OS X Mavericks (10.9.2)
