I have a wide editable grid that requires the user to do some horizontal scrolling. Users complained that when they were editing a cell on the left and they wanted to scroll to the right to edit a different cell, the grid would automatically scroll back to the left as soon as the mouse hovered over any row of data. So you're editing a cell on the left, you click the h-scroll to view the right of the grid and when you move your mouse over a new cell - the grid automatically scrolls back. I'm going to customize our (1.0) grid to make this behavior configurable.
