By "scrolling" can I assume you're referring to the mouse wheel? Well,
naturally I cannot reproduce the problem. As to the scrollbars being tiny
(and that is a great UI feature, imo), that would seem to indicate you
either have a great deal (many rows) of data, or your "active range" is way
screwed up because of data or formatting in the nether regions of your
sheet. Whether that has any connection to the scrolling issue I don't know.

If you want to send me your workbook and the steps to recreate the problem,
I can promise you, at a minimum, some sympathy<g and maybe a solution.
Btw, make sure you have the latest drivers available for your mouse. If an
