I've just purchased an M15 from Best Buy. What I've noticed is that the mouse/touchpad is not working properly. Sometimes when clicking on a window to drag it to another area, nothing will occur. Another thing is the mouse will start moving uncontrollably and scrolling random things I'm trying to read. There are also times when it'll close all the open windows. I thought it perhaps it needed to update since I haven't even had this for a week yet. Did the updates, but still occurring. On a side note, how does one go about removing these annoying fingerprints? Thanks for any input.
