It is Windows 8.1 system. In desktop mode, when i used mouse moving cursor, sometimes it was acted like swipe touch screen on left edge and active an metro program. That is completely unexpected. This is a critical bug to me and unacceptable. It interrupted my normal workflow in desktop operation. It is a design flaw of Windows 8.1 for laptop with touch screen. Using mouse for edge swipe should be disabled in 2In1!
BTW The mouse pad of XPS12 needs to be retested for its user experience. The left button press is on left half side on just on the left corner? confused.
