Hi guys... was trying to do some arranging the other day, but my Surface has decided to not let me use this function anymore! When I hold a finger on a tile, it 'jigs' then a small tick faintly appears in the top right hand corner for about half a second, and a line (kind of like a thin scroll bar) appears at the bottom of the screen. Then whilst still holding down on the tile, it returns to normal like I never touched it. I can still arrange perfectly by using the stylus. Any ideas on this one!?
