I use a Wireless Laser 6000 mouse and it works fine in Excel 2007 Ultimate
on both Windows XP SP2 and Vista Ultimate. You may need to reset the wheel
setting in the Mouse Control Panel. On the Windows Start menu, choose
Control Panel, then Mouse. In that dialog, choose the "Scrolling" tab and
ensure that "Enable horizontal scrolling with tilt wheel" option is checked.

Just upgraded from Excel 2003 to 2007. In 2003 I was able to scroll
horizontal with my Microsoft 6000 laser mouse. Not in 2007. Who can help
me?
