I couldn't find a forum for just the beta, so I'll post here(maybe I just
didn't look hard enough :' ). Anyway, I'd like to find a way to increase the
speed of the scroll for right now it is unforgivablely slow and yes; I have
increased the speed of my mouse to the max. The speed of the mouse's scroll
doesn't seem to effect the speed of scrolling in Excel 2007 Beta 2 but works
great in Excel 2000.

Secondly, I would like to know what happen to the ability to scroll left and
right using a mouse.

Lastly, I'd like to ask a question that I have had since I started using
Excel. Why is there a limit on the number of rows & columns? Why can't
someone choose how many rows & columns to have or when someone gets to the
end, another byte is used to keep going?
