To Scroll:
Click Microsoft Button (Large button top left)
Click Options (Towards bottom right of dialog box)
Click Advanced (Left column)
In Editing Options (First block)
Uncheck Zoom on roll with Intellimouse.
I tried what you suggested but no luck. I don't have an Intellimouse but I
can scroll on everything (including this dialog box and the help dialog box
in Excel 2007) but not in a spreadsheet. It works in the new Word and it
worked in the old version of Excel, but not the new on. Anything else I can
try?
