Windows 2000, Excel 2000

In Excel 2000, when I drag the scroll button on the scroll bar with
the mouse, nothing happens until I release the mouse button (stop the
drag) and then the worksheet "jumps" to the new position. I don't
know where to stop when I am dragging the scroll button, because I
don't see what is happening until after I stop.

With Word and other programs, when I drag the scroll button with the
mouse, the workspace scrolls continuously as I drag and I know where
to stop.

How can I fix Excel to exhibit this latter behavior?

Scrolling by clicking on the scroll arrows does scroll the worksheet
continuously, but it is much too slow for long scrolls.

Thanks,
