I have recently acquired a Microsoft Arc Touch Mouse. It has a Microsoft BlueTrack technology for motion detection. Microsoft claims that it should work on practically any surface. Well, when I use mine on a bedsheets, it works "ugly". It always skips movements, as if I am lifting the mouse. My 10$ logitech with standard red laser works perfect on both table and the bedsheets.
Is it just my BlueTrack problem, or some of you can confirm that this MS technology really can't do it's job as claimed, when it comes to cotton surfaces?
