nope, those work. The horizontal only work with the scroll wheel (which is fine for me - noticed that after I posted), but the horizontal do not work with the pointer and left clicking or dragging. If I drag the scroll bar, it moves, but the fence contents don't and then when I release my mouse button the scroll bar slides right back to its home position at the left. And if I click on the right arrow of the scroll bar, nothing happens. For the vertical each method works. In other programs all works normal.
